INTRODUCTION
The High Density Fiber Distribution Frame User manual documents the ADC High Density
Fiber Distribution Frame (FDFH) system. The FDFH system is intended for use in lineups
with the Lucent Technology LGX fiber distribution frames to provide higher density
interconnect or cross-connect termination for fiber optic circuits than is currently available in
the ADC Fiber Distribution Frames. The FDFH connector modules can also be installed
within an LGX style frame to increase the connector density.
The FDFH frame does not accommodate splice modules, storage modules, or value added
modules (VAMs) which are available in other ADC fiber distribution frames. The FDFH
frame system is not recommended for use in new lineups.
Other ADC fiber distribution frames are the front load (formerly referred to as “standard
style”) Fiber Distribution Frame (FDF) and the rear load (formerly referred to as “IFC style”)
FDF. Less commonly used frames include the Front Facing Fiber Distribution Frame (F3DF)
and the 7-Inch High Module (LGX Style) Frame. Both the front load and rear load style FDFs
require front and rear access to the frame, and both style FDFs use 8-inch high modules. By
contrast, the F3DF is designed for front access only, and the LGX Style Frame is designed for
use with 7-inch modules compatible with the Lucent Technology LGX Frame. Also available
is the Next Generation Frame (NGF) family of fiber frames which includes several sizes of
Fiber Main Distributing Frames (FMDF) and a Maintenance Bay. These fiber distribution
frames are documented in other manuals. For new lineups, the use of the front load FDF, the
rear load FDF, and the FMDF are recommended.
This manual describes both the FDFH frame and the FDFH connector modules, and provides
instructions for their installation and operation. The manual is intended for persons familiar
with optical fiber cable systems and their application. The illustrations and examples in this
manual depict typical installations but they may not be an exact representation of your
installation.

Admonishments
Important safety admonishments are used throughout this manual to warn of possible hazards
to persons or equipment. An admonishment identifies a possible hazard and then explains
what may happen if the hazard is not avoided. The admonishments — in the form of Dangers,
Warnings, and Cautions — must be followed at all times. These warnings are flagged by use
of the triangular alert icon (seen below), and are listed in descending order of severity of
injury or damage and likelihood of occurrence.
Danger: Danger is used to indicate the presence of a hazard that will cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.
Warning: Warning is used to indicate the presence of a hazard that can cause severe
personal injury, death, or substantial property damage if the hazard is not avoided.
Caution: Caution is used to indicate the presence of a hazard that will or can cause minor
personal injury or property damage if the hazard is not avoided.
General Safety Precautions
Listed here are all the general admonishments which apply throughout the procedures in these
instructions.
Danger: Do not look into the ends of any optical fiber. Exposure to invisible laser radiation may
result. Do not assume laser power is turned off or the fiber is disconnected at the other end.
Caution: Always allow sufficient fiber length to permit routing without severe bends. Fibers may
be permanently damaged if bent/curved to a radius of less than 1.5 inches (3.81 cm).

FDFH Frame
As shown in Figure 3 and Figure 4, the network equipment rack provides the basic structure of
the FDFH frame system. It supports the large capacity vertical cable guides (VCGs), the front
doors, and the rear doors.
At each of the four lower connector module locations, 14-inch VCGs are mounted on the front
of both network rack vertical rails. At the top connector module location, 7-inch VCGs are
mounted on the front of both network rack vertical rails.
The front, smoked, polycarbonate front doors, mounted on the VCGs, protect the front sides
of the installed connector modules. The front doors swing down to provide access to the front
of the connector modules. The hinges on the bottom of the front covers are attached to tabs on
the bottom front of the VCGs. The front covers have latches at the top which fit into square
holes on the top front of the VCGs.
The pair of 6 1/2 foot tall metal doors enclose the entire rear of the frame, protecting the rear
sides of the installed connector modules. The doors swing open to the left and to the right to
provide access to the rear of the connector modules.

FDFH Accessories
Accessories (ordered separately) used with the FDFH include the following:
• Interbay Radius Limiter Kit – used when FDFH connector modules are installed in a
Lucent LGX frame. Kit consists of ten 3-1/4-inch high by 5-3/4-inch wide cable troughs,
edge protectors, screws, and an installation drawing. Attach one radius limiter to the rail
on each side of the frame at location where FDFH connector module is installed.
Provides routing of cables and patch cords with a minimum 2-inch radius.
• Fourteen-inch High VCG Kit – used when 216 position FDFH module is installed in
Lucent LGX frame. Kit consists of two VCGs, two end caps which attach to the VCGs
(only used when frame is at end of lineup), edge protectors, mounting screws, and an
installation drawing. VCG is 14 inches (35.56 cm) high by 4 3/4 inches (12.07 cm) wide
by 8-inches (20.32 cm) deep, which is a horizontal capacity of 38 square inches (245.26
square cm). The VCGs attach to each side of the LGX frame, and the connector module
is mounted on the VCG.
• Vertical Cable Ring Retrofit Kit – replaces existing vertical cable rings on both sides
of the Lucent LGX style frame when placing an FDFH frame adjacent to the LGX frame.
Extends depth of the LGX frame from 5 inches (12.7 cm) to 8 inches (20.32 cm) to
match the depth of the FDFH frame. Kit consists of eighteen 3-inch (7.62 cm) high by 33/4-inch (9.53 cm) wide by 8-inch (20.32 cm) deep VCGs, screws, 18 blank labels, and
an installation drawing.
1.2.5
Cable Routing Summary
The FDFH is designed to enforce a consistent manner of routing cables so as to facilitate
rerouting, testing, and network growth. The following topics summarize FDFH cable routing.
1.2.5.1
Outside Plant Cables
Typically outside Plant (OSP) cables are routed to the rear side of off-frame splice modules,
for splicing to either IFC or pigtails. In some cases, OSP cables are broken out, installed with
field connectors, and connected directly to connector modules. The use of OSP cables in the
FDFH is not recommended because the size of the cable required for the high connection
density of the FDFH would be large and could cause routing problems.
Pigtails, sometimes used to make the terminated OSP to connector module link are not
recommended because the distance from the off-frame splice modules to the connector
modules is too great for using standard length pigtails and the size of the pigtails that would
be required by the high density FDFH connector modules would be large enough to cause
routing problems.

ADCP-90-547 • Issue 1 • November 1999
1.2.5.2
Intrafacility Fiber Cables
IFC cables are used with the FDFH to provide an indoor link between terminated OSP cables
and connector modules. One end of the IFC cable is spliced to the OSP cable within an off-frame
splice unit. The other end of the IFC cable is connected at a connector module in the FDFH.
IFC cables are clamped by cable clamps that mount on the side, towards the rear of the connector
module. However, unlike OSP cables, IFC cables do not need to be grounded. IFC cable enters
the connector module through entry points directly under the cable clamp. Routing of cable subunits and fibers is accomplished through the rear of the connector modules.
1.2.5.3
Frame Grounding
A ground wire lug, an 8-foot length of No. 6 tinned solid copper wire, and six nylon cable clamps
with screws are shipped with the FDFH frame for grounding the frame to the facility ground.
1.3 Physical Description
This subsection contains a physical description for each of the main components of the basic
FDFH system. Included are the network equipment rack with guard box and extension rail,
front doors, rear doors, cable management, and connector modules.
1.3.1
1.3.1.1
FDFH Frame
Network Equipment Rack
The network equipment rack provides the basic structure for the FDFH. It is an industrystandard 7-foot high, 23-inch wide, 12-inch deep unequal flange network equipment rack
conforming to Western Electric Company (WECO) specifications. An extension rail extends
the front of the guard box 3 inches (7.62 cm) , making the depth of the FDFH guard box flush
with the VCGs and front doors. Figure 8 shows the components and dimensions of the
network equipment rack.
As shown, the network equipment rack has pre-drilled mounting holes and front and rear floor
guards. The mounting holes are spaced 1-inch (2.54 cm) apart and are tapped for #12-24
screws. The guard box includes a front box cover with a 3-inch (7.62 cm) extension guard rail
and a 2-inch (5.04 cm) rear guard box. The network equipment rack is made of cold rolled
steel and painted putty white.

Vertical Cable Guides
Both the 14-inch high and the 7-inch high VCGs are 4-3/4 inches (12.07 cm) wide by 8 inches
(20.32 cm) deep, a fiber capacity of 38 square inches (245.26 cm). The VCGs are attached to
the vertical rails on each side of the frame. Vertical tabs at the rear of the VCGs support the
connector modules. Horizontal tabs at the bottom front of the VCGs support the hinges for the
front doors. Two rectangular holes at the top front of the VCG receive the two front door
latches. The VCGs are made of cold rolled steel and painted putty white. Plastic edge
protectors are installed on the VCGs to protect the fiber cables.

1.3.1.3
Front Doors
Five flame retardant, smoked polycarbonate doors are attached to the front of the VCGs. Four of
the doors are 14 inches (35.56 cm) high and are mounted on the 14-inch high VCGs. One of the
doors is 7 inches (17.78 cm) high and is mounted on the 7-inch VCG at the top of the frame.
1.3.1.4
Rear Doors
Two full vertical length doors are mounted on the rear of the frame. The doors completely
enclose the rear of the frame to protect the fiber cables that are outside the connector modules,
but within the rear area of the frame. Recessed handles for pulling the doors open are located
in the middle of the doors. Snap-In magnetic catches at the top and bottom of each door hold
the doors in the closed position The rear doors are designed to accept a padlock for added
security. The rear doors are made of steel and painted putty white.
1.3.1.5
Frame Cable Management
The cable management system provides a means to secure and route patch cords on the FDFH
frame. Figures 3 and 4 show the frame cable management system. It consists of large, high
capacity VCGs, an upper horizontal cable trough, a lower horizontal cable trough, cable tie
brackets, and interbay radius limiters.
VCGs form a high capacity vertical channel for routing patch cords from the connector
modules to the horizontal troughs or to overhead cableways, such as the ADC FiberGuide
system. Service loop storage is provided by the VCGs on the front of the FDFH frame. Excess
length should be chased to the FOT if possible.
The horizontal lower and upper cable troughs are used to route patch cords between opposite
sides of a single bay frame or between frames in a multi-bay lineup. The horizontal cable
troughs span the width of the frame and are mounted on the vertical rails. The upper cable
trough is 3 1/4 inch (8.26 cm) high by 8 inches (20.32 cm) deep. The lower cable trough is 10
inches (25.4 cm) high by 8 inches (20.32 cm) deep. A warning label is attached to the front of
the lower horizontal trough. The label cautions users not to view the light source with optical
instruments. The lower trough is made of aluminum and painted putty white. The upper
trough is made of cold rolled steel and painted putty white.
The interbay radius limiters with edge protectors are used when an FDFH frame is installed
next to another FDFH frame or next to an LGX frame. The interbay radius limiters are
mounted on the adjacent vertical rails of both frames. They are used to loop patch cord slack
within the VCGs, ensuring that cable bends do not exceed a 1.5-inch radius. The interbay
radius limiters are made of cold rolled steel and painted putty white.
Six cable tie brackets are attached to the exterior side of each frame rail. The cable tie
brackets provide a means for securing cables to the frame as they are routed from overhead.
The cable tie brackets are made of flat wire and painted putty white.
The dimensions of the FDFH frame are shown in Table 1.

The two connector plates, identified in Figure 5, provide mounting points for 216 adapters,
The adapters can be mounted at an angle, which eliminates the sharp bends that often occur
when patch cords are routed away from straight-mount type adapters. The angle-style adapters
require special angled retainers which hold the adapters to the connector plate. Each connector
plate holds 108 adapters. Each adapter is numbered on the front of the connector plates.
The module mounts from the rear of the frame on the VCGs that are attached to the frame. Using
the bottom bracket cutouts, the brackets are attached to the two tabs on the rear of each VCG.
Two designation cards, shipped with the connector module, are used to summarize where each
connected patch cord is routed. Four included adhesive backed card holders are used to mount
the designation cards on the back of the front door. The card holders orient the cards for
reading when the door is closed. When the door is opened, the card holders allow the cards to
be re-oriented for writing.
1.3.2.2
14-Inch Connector Module Cable Management
The 14-inch high, 216 position connector module cable management features, used to secure
and guide cables and patch cords in the connector module, consists of the following items that
are mounted on the outside and the inside of the connector module (see Figures 5 and 9):
• On the outside of the connector module, a cable clamp kit, with mounting plate,
standoffs, and grommet.
• Within the connector module, two radius limiter plates with two radius limiters, two
fanout clip holders with o-rings, two lacing tabs, and one fanning strip mounted on each
of the radius limiter plates.
• Within the connector module, two radius limiters, two fanout clip holders with o-rings, three
lacing tabs, and one fanning strip mounted on the bottom of the connector module chassis.
• Kurly locs, shipped with the connector modules, used to hold fibers and cable sub-units
together.
The dimensions of the 14-inch connector module are shown in Figure 10 and in Table 2.
Connector module weight is in Table 2.
The rear door encloses the rear of the connector module and protects cabling within the module.
The door is made of steel and has hinges at the bottom and latches at the top. The latches, when
released, allow the door to swing down, providing access to the rear of the module.
The connectors that are available for use in the connector module are singlemode SC,
singlemode FC, singlemode SC/8° angled polish and FC/8° angled polish. Table 2 gives
functional specifications for these connectors

INSTALLATION
This section provides guidelines and procedures for installing an FDFH frame and connector
modules. Installation includes such activities as unpacking, mounting, and grounding the
frame; installing connector modules; routing cables; setting up the connector modules; and
connecting cables to the connector modules.
The procedures required in a specific installation depend on how the connector modules were
equipped at the factory, per customer order. The connector modules may be loaded with cable
and installed connectors, or cable may need to be installed and terminated. The items
described in this section may or may not be present. For items that are present, however, the
corresponding procedures apply.
This section assumes that installation planning is complete and that the installer is working
from a general installation plan. If there are questions regarding installation, consult ADC’s
Application Engineering group (1-800-366-3891) for assistance.
2.1 Frame Installation
This subsection provides procedures for anchoring and grounding the frame. The actual
location and installation sequence of each frame should be specified in the installation
drawings. Figure 11 shows the rack top and bottom mounting dimensions and footprint.

2.1.1
Unpacking and Inspecting the Frame
Remove the FDFH from the shipping container and inspect it for damages. If there are any
damaged or missing parts, file a claim with the commercial carrier and notify ADC Customer
Service. Refer to the General Information section at the rear of this manual for the
repair/replacement procedures.
If there are no damaged or missing parts, check all screws used to secure the various parts of the
frame to the rack. Tighten any fasteners that may have become loose during shipping.
2.1.2
Mounting the Frame on a Concrete Floor
Caution: Always use protective eye wear, gloves and clothing when working with tools such
as electrical drills for installing equipment.
When mounting the frame on a concrete floor, first ensure that the appropriate hardware is
available. Typically, four anchors are used when racks are floor supported and two anchors
when supported from overhead. In earthquake zones it is recommended to always use four
floor anchors. The anchor is designed with a threaded rod (stud), torque nut, and torque nut
cap. The torque nut cap will break away when tightened to the proper torque pressure. Anchor
the rack to the floor using the following procedures.
1. Position the rack in its designated floor location.
2. Mark the mounting hole locations on the floor. Use the holes with the widest spacing to
provide the greatest stability. See Figure 12.
Note: For maximum anchor holding strength, select exact drill size for hole drilling.
3. Move the rack out of the way. Drill an 18 mm diameter hole to a depth of 3.15 inches
(80 mm) in the concrete. Clean out hole with compressed air or blow-out bulb. Check the
hole depth with a tape measure or by placing the assembled anchor bolts in each hole. If
reinforcing bar is encountered while drilling, relocate the hole. Fill the unusable hole
with locally approved filling product.
4. Select the anchor assembly. Ensure that the stud is not extending beyond the bottom of
the wedge. Insert the assembly into the hole and tap into place with a hammer. Check
that the shoulder of the anchor is even with the floor. See Figure 12.
5. Use a deep socket or box-end wrench and tighten the torque nut until the anchor is just
snug. Do not tighten until the torque nut cap breaks way.
6. Remove the torque nut and washer from the anchor assembly.
7. Position the rack over the anchors. Level the rack using shim plates as required. See
Figure 13.
8. Place the load spreader plates, one or two square washers as required, over the stud.
Replace the flat washer and torque nut onto the stud. Tighten the torque nut until the
torque nut cap breaks away, indicating the anchor is properly set. Discard the breakaway portion of the torque nut cap.

2.1.3
Equipment Rack to Cable Runway (Rack) Support Framing
Cable runway support framing provides two functions, top support for floor supported
(anchored) equipment racks, as shown in Figure 14 and support for cable racking, as shown in
Figure 15. Threaded rod, clip “J” bolts, metal clips, hanger brackets and hex nuts secure the
top of equipment rack and cable rack to the support framing. Support for two level cable racks
is shown in Figure 16.
Note: It is recommended that the top supports run perpendicular to the rack. This will
provide as much clear space as possible for cabling.
2.1.4
2.1.4.1
Grounding the Frame
Standard Grounding Kit Installation
The standard grounding kit included with the FDFH frame consists of a length of #6 solid
copper, tinned wire with attached lug connector, nylon wire clips, and screws. The #6 wire is
8-feet long and mounts on either the left or right side at the rear of the frame. The #6 wire
connects to the frame through the grounding lug. To connect the frame to the overhead office
ground connector, use either a length of wire (not provided), or the H-TAP Grounding kit
available separately.
Use the following procedure to install the included grounding kit:
1. Remove the plate with magnetic door latches at top of frame.
2. Locate the point at the top of the frame where the lug connector (attached to the #6 wire)
fastens to the frame as shown in Figure 17.
3. Make sure the attachment point for the lug connector is clean and free of paint.
4. Apply a coating of NO OX grease (not provided) to the lug connector attachment point
to prevent corrosion.
5. Secure the lug connector and the wire to the overhead ground conductor (if used) using
two 12–24 × 1/2 inch screws as shown in Figure 17.
6. Uncoil the roll of #6 wire (attached to lug) and route it down the rear side of the frame.
7. Use the six wire clips provided to secure the #6 wire to the frame. See Figure 17.
8. Trim off the excess wire length at the bottom of the frame and then securely tighten each
wire retainer.
9. Reinstall the plate with magnetic door latches.

door in the position shown in the installation drawing.
2.3 Cable Installation
This section provides guidelines and procedures for connectorizing and installing IFC cables
in the FDFH frame and connector modules.
Danger: Do not look into the ends of any optical fiber. Exposure to invisible laser radiation may
result. Do not assume laser power is turned off or the fiber is disconnected at the other end.
Cables are typically routed from an overhead cable system to the FDFH. The cables are routed
downward along either the left or right side of the FDFH frame. The cable route is along the
frame vertical where cables are tied to the cable tie brackets on the vertical using cable ties or
cord, then to the cable clamps on the sides of the connector modules.
2.3.1
Connectorizing IFC Cable
Single-tube IFC cable (such as Lucent Unitube™ or Alcatel Uniribbon™), in which a single tube
within the common outer wall contains all of the component ribbons or strands, is used in the FDFH.
The sub-units broken out from single-tube IFC cable are relatively unprotected and require the
additional protection provided by a flare tube and cap with strain relief inserts, buffer tubing,
heat shrink tubing, and double sided tape. See Figures 22 and 23. The flare tube and cap are
installed at the breakout point of the cable below the cable clamp. For the 216 position
connector module, a 216-fiber ribbon cable is split into 18 sub-units of 12-fibers. For the 96
position connector module, the 96 fiber ribbon cable is split into eight 12-fiber sub-units. A
protective tube is installed on each sub-unit. The sub-unit protective tubes are then inserted on
one end through the strain relief inserts in the flare tube cap into the flare tube and on the
other end into fanout clips. See Figure 24.

Prepare the fiber cable for installation in the connector module as follows:
1. Determine the length of cable required to route the fibers from the clamp point to the
cable termination point. Ensure sufficient length is provided for installation of the
connectors. (Note the cable fibers will be looped around the radius limiter plate once.)
2. Press the strain relief inserts into a flare tube cap capable of containing a 108 to 216 fiber
ribbon cable (216 position connector module)or a 60 to 96 fiber ribbon cable (96
position connector module) as shown in Figure 22.
3. Secure a flare tube capable of containing a 108 to 216 fiber ribbon cable (216 position
connector module) or a 60 to 96 fiber ribbon cable (96 position connector module) onto
the cable using the following steps (see Figure 23):
a. Slide a 3.0-inch (7.62 cm) length of 1-inch (2.54 cm) ID heatshrink tube over the cable.
b. Wrap a 0.032-inch (0.081 cm) thick by 1.75-inch (4.45 cm) wide double-sided foam
tape around the cable two times (see Figure 23).
c. Slide the flare tube onto the cable until it stops (see Figure 23).
d. Apply heat to the heat shrink tube until it shrinks down around the cable (see Figure 23).
e. Split each ribbon evenly down the middle and stack the two halves one on top of the other.
f. Fish the ribbons through the flare tube, flare tube cap holes, and strain relief inserts.
g. Press the flare tube cap into the flare tube firmly until a clicking sound is heard,
indicating that the cap is in place on the tube (see Figure 22).
h. Slide protective tubing over the ribbons and over the strain relief inserts.
4. Mark the location of the fiber breakout point on the sub-unit protective tubes where the
fanout clips will be installed.
5. Beginning at the fiber breakout point, strip off the protective tube to expose the
individual fibers. Clean any cable filling from the fibers.
6. Cut 900 micron buffer tubing for individual fibers to fanout length minus 1.0 inch (2.54
cm) and carefully place over the fibers.
7. Open the fanout clip and fill it with RTV. Place the end of the protective tubing into the
fanout clip. Place the fibers with buffer tubing into the fanout clip and close the fanout
clip (see Figure 24). Repeat for all fanout clips.
8. Mount the connectors on each separate fiber according to the connector manufacturer’s
instructions. Apply designation tags to each fiber as each connector is installed.
2.3.1.1
Installing Connectorized IFC Cable in 216 Position Connector Module
Danger: Do not look into the ends of any optical fiber. Exposure to invisible laser radiation may
result. Do not assume laser power is turned off or the fiber is disconnected at the other end.
Install connectorized IFC cable (factory or field assembled) in the connector module as
follows:
1. Turn the latches and open the rear door on the connector module. Use a large blade
screwdriver in the latch slot to turn the latch if necessary. Lift the door up to remove it
from the openings in the hinges.

the fanout clip holder by stacking them horizontally. Place rubber o-rings over the fanout
clips and around the fanout clip holders to hold the fanout clips in the holders.
5. Route the fibers in buffer tubes to the right, around the two radius limiters to the rear of
the fanout tree. On the middle and top levels, place two 1-inch lengths of convoluted
tubing around the buffer tubes and wrap tape around the convoluted tubing to hold it in
place as shown in Figure 27 and 28. Tie the convoluted tubing to the lances on the radius
limiter plate. Secure the fibers in buffer tubes together using kurly locs at the points
shown in Figures 27, 28, and 29. Route six fibers through each hook on the fanning tree.

The front door is opened by turning the two latches at the top of the door 1/4 turn and
swinging the door downward. To close the door, swing it upward and twist the latch 1/4 turn.
3.3 Connector Module Rear Door Operation
The rear door is opened by turning the two latches at the top of the door 1/4 turn and swinging
the door downward. To close the door, swing it upward and twist the latch 1/4 turn.
3.4 Routing Patch Cords
Patch cord routing is determined by the configuration of the IFC and FOT connections. In an
interconnect system, patch cords from FOT equipment are connected to a corresponding IFC
termination at the connector panel. In a cross-connect application both FOT and IFC
terminations are made at the rear of the connector panel. A patch cord is used at the front of
the connector panel to connect any two IFC circuits, or to connect an IFC circuit to a
designated FOT circuit. Figures 31 and 32 illustrate the two configurations.
3.4.1
Routing Interconnect Patch Cords
Danger: Do not look into the ends of any optical fiber. Exposure to invisible laser radiation may
result. Do not assume laser power is turned off or the fiber is disconnected at the other end.
In an interconnect system, equipment patch cords are connected to the front of the connector
plates while the IFC circuits are terminated at the rear. The interconnect patch cords are routed
from the front of the connector module to the left or right side of the module into the VCG for
routing to the FOT equipment. Ensure that all patch cords are routed with no less than a 1.5inch (3.8 cm) bend radius. Excess patch cord length can be stored in the VCGs, at the FOT
equipment, or at an intermediate storage device. An interconnect application is shown in
Figure 31.

3.4.2
Routing Cross-connect Patch Cords
In a cross-connect configuration, FOT equipment and IFC fibers are terminated at the rear of the
connector plates. A patch cord is used to cross-connect the front of the appropriate FOT
termination with the front of the appropriate IFC termination. Cross-connections can be made
between terminations on the same module, between terminations on different modules (same
frame), and between terminations on different frames. Patch cords are routed through the VCGs
and the top and bottom cable troughs. Ensure that all patch cords are routed with no less than a
1.5-inch (3.8 cm) bend radius. Excess patch cord length can be stored in the VCGs and cable
troughs or at a nearby storage panel. A cross-connect application is shown in Figure 32.

MAINTENANCE
This section provides information related to maintenance of the connector module. The
information provided in this section is listed below:
• Series Test Access
• Temporary Service Restoration
• Moving Optical Fiber System To New Equipment
• Repair Procedures
• Reconfiguring A Fiber Optic System
• Disassembly
The series test access, temporary service restoration, and moving optical fiber system to new
equipment procedure requires opening the circuit undergoing test. This will interrupt service
on that circuit.
Danger: Do not look into the ends of any optical fiber. Exposure to invisible laser radiation may
result. Do not assume laser power is turned off or the fiber is disconnected at the other end.
4.1 Series Test Access
Series testing can be used to test a disabled optical system. Series test access to the circuits is
available at each of the connector modules. Series testing requires that a connection be
removed which will interrupt service. For bidirectional transmission, transmission in both
directions will be interrupted.
This procedure is used to obtain series test access to the fiber optic terminal equipment or the
IFC cable at the frame. The appropriate test equipment may then be connected to the IFC
circuit or FOT equipment that requires testing. See Figure 33 for a schematic diagram of this
procedure.
4.1.1
Series Test Access – Interconnect Applications
1. Locate the adapter/receptacle that serves as the termination point for the IFC circuit or
FOT equipment that requires testing.
2. Disconnect the FOT equipment patch cord connector from the front side of the
adapter/receptacle located in step 1.
Danger: Do not look into the ends of any optical fiber. Exposure to invisible laser radiation may
result. Do not assume laser power is turned off or the fiber is disconnected at the other end.
3. Connect appropriate test equipment to the IFC circuit adapter/receptacle or the FOT
equipment patch cord. Note that a separate patch or test cord with the proper adapters
may be needed to make connections to the test equipment.
4. Install dust caps on all adapters and connectors that will not be used during the test.

4.1.2
Series Test Access – Cross-Connect Applications
1. Locate the adapter/receptacle that serves as the termination point for the IFC circuit or
FOT equipment that requires testing.
2. Disconnect the cross-connect patch cord connector from the front side of the adapter/
receptacle located in step 1.
Danger: Do not look into the ends of any optical fiber. Exposure to invisible laser radiation may
result. Do not assume laser power is turned off or the fiber is disconnected at the other end.
3. Connect appropriate test equipment to the IFC circuit adapter/receptacle or the FOT
equipment adapter/receptacle. Note that a separate patch or test cord with the proper
adapters may be needed to make connections to the test equipment.
4. Install dust caps on all adapters and connectors that will not be used during the test.
4.2 Temporary Service Restoration
The interconnect and cross-connect capabilities of the connector module allows service
restoration on either a temporary or permanent basis. Interconnect, cross-connect, or
combinations of both capabilities can be used to restore service to one or more circuits so long
as the circuit to which service is transferred is terminated on the same network.
This procedure can be used to temporarily restore service if an IFC cable has been cut or
damaged. To perform this procedure, a spare IFC circuit must be available. See Figure 34 for
a schematic diagram of this procedure.
4.2.1
Temporary Service Restoration – Interconnect Applications
1. Locate the adapter/receptacle that serves as the termination point for the damaged IFC
circuit.
2. Disconnect the FOT equipment patch cord connector from the front of the adapter/
receptacle located in step 1.
Danger: Do not look into the ends of any optical fiber. Exposure to invisible laser radiation
may result. Do not assume laser power is turned off or the fiber is disconnected at the other
end.
3. Locate the adapter/receptacle that serves as the termination point for the spare IFC
circuit.
4. Route the FOT equipment patch cord to the adapter/receptacle for the spare IFC circuit
and mate patch cord connector with adapter/receptacle. If patch cord is too short, select
and route a new patch cord between the FOT equipment and the adapter/receptacle for
the spare IFC circuit.
5. Install dust caps on all unused adapters and connectors.

patch cord is too short, select and route a new cross-connect patch cord between the
spare IFC circuit adapter/receptacle and the FOT equipment adapter/receptacle. Mate
patch cord connectors with adapter/receptacles.
5. If a new cross-connect patch cord was installed, remove the old cross-connect patch cord
from the frame.
6. Install dust caps on all unused adapters and connectors.
4.3 Moving Optical Fiber System to New Equipment
Fiber optic systems do not typically support large scale cutover to new equipment without the
addition of other switching equipment to provide a bridging capability. The following
procedure describes how individual circuit transfers can be made.
This procedure is used to disconnect an IFC circuit from its present equipment and re-connect
it to new equipment. See Figure 35 for a schematic diagram of this procedure.
4.3.1
Moving Optical Fiber System to New Equipment – Interconnect Applications
1. Locate the adapter/receptacle that serves as the termination point for the IFC circuit that
is to be connected to new equipment.
2. Disconnect the FOT equipment patch cord connector from the front side of the adapter/
receptacle located in step 1.
Danger: Do not look into the ends of any optical fiber. Exposure to invisible laser radiation may
result. Do not assume laser power is turned off or the fiber is disconnected at the other end.
3. Select and route a new patch cord between the new FOT equipment and the
adapter/receptacle for the IFC circuit. Mate patch cord connector with
adapter/receptacle.
4. If necessary, remove the old FOT equipment patch cord from the frame and overhead
guideway system.

5. If a new cross-connect patch cord was installed, remove the old cross-connect patch cord
from the frame.
6. Install dust caps on all unused adapters and connectors.
4.4 Repair Procedures
Repair of the connector module will likely involve only replacement of a defective fiber,
bulkhead adapter/receptacle, or mechanical component. No special tools or procedures are
needed for component removal and replacement.
4.5 Reconfiguring a Fiber Optic System
Interconnect and cross-connect methods can be used to permanently or temporarily
reconfigure the optical circuits.
4.6 Disassembly
Disassembly of the module, or removal of the module from the frame is essentially the reverse
of the installation process. Disassembly may involve removal of one or more modules from
the frame.
The following procedure describes how to remove a connector module from the frame.
1. Remove from service, that portion of the fiber optic system terminated at the connector
module being removed.
Danger: Do not look into the ends of any optical fiber. Exposure to invisible laser radiation may
result. Do not assume laser power is turned off or the fiber is disconnected at the other end.
2. Open the front door; then identify and disconnect all interconnect and cross-connect
patch cords at the front of the connector plates.
