ODN4P
Optical Distribution Node, Four Ports
About the Product
The Light Link® Series 2, deep-fibre Optical Distribution Node ODN4P is a prime building block for highperformance networks, designed for adaptability, scalability and optional return-path segmentation. The
configuration options are well suited for Hybrid Fibre Coaxial (HFC) networks with smaller nodes and very
high traffic handling capability for Internet and telephony.
This node employs advanced modular technology to provide a cost effective and flexible solution for
expanding network architectures.
The optical distribution node may be configured with one optical receiver for a single-fibre feed, or two optical
receivers with an automatic AB protections switch for ring networks. The return path can be equipped with
one uplink transmitter for all four RF ports, but segmentation is possible with two, three or four uplink
transmitters. With four uplink transmitters there is an optional CWDM filter to put all segments on one return
fibre.
The node features very high RF level outputs up to 1000 MHz and in many instances no line extender
amplifiers would be needed. However, each RF port has also a power inserter to facilitate remote powering of
line extender amplifiers when so required by network planning.
The ODN4P node return-path transmitters include a 4.5 MHz pilot generator for easy return path alignment.
When used with the PBN RPQRM return-path receivers, fully automatic RF gain control is possible. The pilot
also carries an FSK signal with all vital node monitoring parameters and this data is available in the headend
on the chassis display as well as in SNMP format for use in management networks.

(1) Specifying 2 forward-path receivers without a protection switch module implies segmented forward-path operation. RF ports 1&2 are connected to optical RX1,
and RF ports 3&4 are connected to optical RX2, allowing forward-path segmentation. Requires [T] = 4.
(2) Specifying 1FR without return transmitter or with one return transmitter only in the order code implies a 1 x 4, 4 x 1 node configuration, i.e. a single return path for
all four coax ports. The return transmitter is supplied as standard with low pass filter. ODN4P-RT-LP-[X]-[Y]-[Z].
(3) Specifying two return transmitters implies 2 x 2 return path segmentation, i.e. TX1 connects RF ports 1 & 2, TX2 connects RF ports 3 & 4.
(4) Available only when [V] = 1. Specifying 4DFBS with four return transmitters in the order code implies a 1 x 4, 4 x 1 segmented node configuration, i.e. a single
optical receiver 1 x 4 shared forward path but a 4 x 1 segmented return path with a separate return transmitter on 1510 nm, 1530 nm, 1550 nm, 1570 nm for each of
the four coax ports. This configuration includes a ODN4P-RWDM for single return fibre operation.
The ODN4P optical distribution node is capable of being equipped with two power supply modules and five rx/tx/switch modules at any one time. The node can
accommodate a maximum number of two forward receiver modules and a maximum number of 4 return transmitter modules. The RXAB switching module occupies
one of the five module slots.
Specialized configurations may be available upon customer request. Consult with PBN Engineering for details.

Note 1: Specify and order attenuator pads and equaliser pads separately if the customer requirements differ from the factory defaults.
The default pads supplied with the nodes are 3dB attenuator pads and 14 dB equalisers. Standard equalisers are for 870 or 1000 MHz
systems. Equalisers for legacy systems with other bandwidths like 450, 600, 750 MHz are specials. Please add the required bandwidth
to the model code.
Note 2: If a node is ordered for forward path only, then the return path attenuators are not installed and not part of the delivery. Retrofit
of an ODN4P-RT transmitter also requires four units ATT4P to be installed. If a node is ordered with return path fitted, then the 4 x
ATT4P pads will be pre-installed and part of the delivery.
