Introduction
A SOSA (Splice Only Sub Assembly) is an assembly of a number of trays mounted on a base plate. Splicing in the
single element trays is on a cable element basis (max.8 fibers) , splicing in the single circuit trays is on a two-fiber
(transmit and receive) basis. A SOSA-SE assembly has 2 or 4 single element trays. A SOSA-SC assembly has 4 or
8 single circuit trays.The base plate allows the trays to hinge, giving access to all fibers.
Note: The user must be aware that this product is specifically designed for the fiber optic network and should be
handled with care to prevent damage which may be caused by dropping the product or its
contents.
When products are operational network elements for fiber, infrastructure can contain fiber ends carrying an
optical signal. Laser irradation can cause serious eye damages. Follow all local safety regulations.
To clean FIST components, the use of isopropylalcohol is recommended.

SEC0 4, SECO 6, FOPT-SF, FOPT-CS, FOPT-CT
In the following installation instructions both SECO 4 and SECO 6 are
covered.
SECOs are used to convert loose tube cable elements into circuit
elements.
A SECO 4 is used to convert a loose tube with 8 fibers into
4 single circuits.
A SECO 6 is used to convert a loose tube with 12 fibers into
6 single circuits.
A SECO is clicked onto the FAS plate.
SECOs and transportation tubes are in some FIST products
pre-installed.

Kit contents SOSA
Three sizes of transportation tubes are used for guiding the fibers to
the SECO and from it to the splicing trays.
A FOPT-SF:
Ø 1.2 x 1.8 is used to exit the SECO towards the splicing trays.
B FOPT-CS:
Ø 2.4 x 3.1 is used to enter the SECO.
C FOPT-CT:
Ø 3.15 x 4.3 is used to make the transition from the loose tube to the
FOPT CS.
If the FOPT CS fits over the loose tube, the FOPT CT is not
needed.

Installation
3.1
SOSA installation
3.1.1 To fit a module: open the module in the middle, hold the
module base, push and slide it onto the FAS module area as close as
possible to the FAS entrance area positioned in the correct way; i.e. the
back of the trays should face the FAS entrance area. Do not leave any
space between the different modules. Make sure that the module is
positioned properly before clicking it onto the FAS and check the snap
fit before continuing! Make sure SOSA is clicked in well. Identify the
module and number the trays.
3.1.4 Identify the tray to be worked on and make it accessible. If the
FAS module area/trays are in the vertical position you will have to
support the trays above the selected one using the tray wedge. The
wedge is located in the spare hinge holes between trays, and attaches
to the back of the first of the upper trays (snap fit).
3.1.5
The SOSA module base is numbered.
3.1.2 To remove the module: carefully lift the base at the centre of
its length with the lip and push the base at the other side.
3.1.3 SECOs are mounted according to the installation instructions
of the network element concerned. The first step is to define how
many FOPT-SF will be needed for each SECO. SC trays will be fed by
one FOPT-SF tube, containing 1 or 2 fibers. SE trays will be fed by a
maximum of 8 fibers in one FOPT-SF tube.
3.1.6. For SC trays, tray 1 has to be fed from groove 1, tray 2 from
groove 2, etc.
3
SE trays have double thickness, so use the odd number grooves, i.e.
tray 1 to be fed from groove 1, tray 2 from groove 3, etc. or use two
grooves per tray if entering with two FOPT-SF is needed.
3.1.9 Cut the FOPT-CS to the appropriate length, using the
FACC-tube-cutter 01, strip the loose tube and clean the fibers. The
fibers need to be cleaned thoroughly so that they will not stick during
feeding.
Separate the fibers and guide them into the FOPT-CS. Insert the
FOPT-CT over the loose tube so that there is an overlap of at least
10 mm.
3.1.7
Each FOPT SF tube that will leave a SECO should be cut to the
correct length, depending on the tray to be fed.
Guide the FOPT-SF to the incoming side of the tray and push the tube
into the groove under the tray until it will go no further.
3.1.10 Mount the SECO on the FOPT-CS.
3.1.8
Cut the tube 10 mm from the SECO.
3.1.11 If necessary, divide the fibers into circuits and place each
circuit in an outgoing port of the SECO (dark fibers should be placed on
top ports).
Do not click the SECO onto the FAS plate yet.
4
3.1.12 Insert and feed the fibers into the selected tube (FOPT-SF) until
they appear at the opposite entrance to the tray.
Take the fibers and pull the remaining length gently through the tube.
3.1.13. Place the FOPT-SF in the SECO.
3.1.14 To avoid buckling of fibers in the transportation tubes pull
gently on the fibers and store the fibers temporarily on a tray.
3.1.15
Storing dark fibers can be done in three different ways
1) Organize dark fibers into the diffrent trays, following instructions as
described
2) Store all dark fibers together (with a max. of 24) in the firs
available SE-tray;
3) Store all dark fibers into the dark fiber storage area. If using the dark
fiber storage area, cut the FOPT-SF for each circuit so that the FOPT-SF
sits 20 mm inside the dark fiber storage area.
Click the SECO onto the FAS-plate.
3.1.16
By using KTUs, maximum two secondary coated fibers
should be passed through the KTU in accordance with individual
installation instructions. No SECO is required.
5
In SC-trays semi tight coated fiber can be used. The coating will be
stripped 100 mm beyond the KTU.
When using pigtail fibers with a non-flexible coating in SE-trays, the
coating will have to be stripped also.
Note: when entering with two FOPT-SF in one groove, cut them in such
a way that they are positioned 20 mm inside the groove on top of each
other.

3.2.3 Take the splice protector, and turn it 180 degrees.
Put the splice protector centered towards the splice holder.

3.2.1 Take the stored fibers out of the tray (a fiber guiding pin can be
used).

3.2.2
Splice the fibers and put the splice protector.

3.2.4 Make several loops, and place the fibers on the tray .
Avoid tight wrapping around the centre of the tray. If the length of the
fiber between the tray entrance and the splice is less than 900 mm it
may be difficult to store the fiber on the tray and re-splicing to a correctly cut length may be necessary.
3.2.6 A tray-lid has to be positioned on the tray for the last tray on
the FAS.
To remove the traylid, pull the lid on the bottom.

•
•
•
•
•
Make sure the grooves on the FAS are clean.
Cut the transportation tubes with the tube- cutter.
Cut the FOPT-SF 10 mm from the SECO (3.1.8).
Push the FOPT-SF + FOPT-CS completely in the SECO.
Avoid buckling of the fibers (3.1.14).
Initial fiber lenght is 1,5 m.
Leave the 10 mm gap between FOPT-CT and FOPT-CS.
3.3.3 SC-tray routing with the use of the windows.
The apertures are labelled by the letters A, B, C or D so that they can be
referenced in instructions.
A and C are for Transmit fibers, B and D for Receive fibers.
