About fiber-optic cables

NOTE:
It is important to label every cable that you install. For details, refer to the section, Labels
for Fiber-Optic Cables, in Appendix E of DEFINITY® Communications System Generic 3
V4 Implementation (555-230-655).
NOTE:
Throughout these procedures, remember to keep track of which fiber is attached to which
connector on each lightwave transceiver. This section provides figures offering the
suggested way of making these connections.
The connectors on the lightwave transceivers are labeled either TX (transmit) or RX
(receive), while the fibers attached to each connector are numbered either 1 or 2. A viable
fiber connection is only made when both fibers in each cable (that is 1 and 2) route from
the TX connector of a port network to the RX connector of its adjacent port network. For
an example, refer to
reliability adjacent cabinets),
NOTE:
For implementation details, refer to the "Fiber Link Administration" sections of
DEFINITY® Communications System Generic 3 V4 Implementation (555-230-655).

These distance limitations are approximate measurements of the actual fiber right-of-way
(not of the shortest linear distance) between the two endpoints.
Connecting standard or high reliability
adjacent cabinets
When a standard-reliability PPN and EPN are collocated, one fiber-optic cable (FL2P-P-XX) and two
lightwave transceivers (9823-type) are required to connect the EPN.
NOTE:
For the FL2P-P-XX fiber-optic cable, the -XX suffix represents the length of the cable in
feet. Based on floor-plan considerations, the length of these cables may vary. However,
20-foot cables are normally adequate for a Release 8si with two port networks.
