Interconnect Port Networks with Fiber
Optic Cabling
Follow the procedures for conceding all the port networks, depending on the type
of reliability:
■
Standard Reliability
■
High Reliability
■
Critical Reliability
Standard Reliability
After all fiber optic equipment is installed, refer to Appendix A, ‘‘Fiber Link
Administration’’ .
NOTE:
Keep track of which fiber attaches to which connector on each lightwave
transceiver. Label every cable installed. This section provides figures
showing typical examples of these connections.
The connectors on the lightwave transceivers are labeled TX (transmit) or RX
(receive), while the fibers attaching to each connector are numbered either 1 or 2.
See
Figure 4-10 .
Collocated Port Networks
For a standard reliability system with 1 collocated EPN, use 1 fiber optic cable and
2 lightwave transceivers to directly connect the networks.
For a standard reliability system with 2 collocated EPNs, use 3 fiber optic cables
and 6 lightwave transceivers to directly connect the networks.
NOTE:
Based on floor plan considerations, the length of these cables may vary.
20-foot (6.1 m) cables are normally adequate for 2 PNs.
For collocated cabinets, route the fiber optic cables directly from the PPN to each
EPN cabinet. Because a PPN cabinet is collocated with a Single-Carrier Cabinet
(SCC1) stack, the preferred routing is to run the cables down the cable tray and
out the bottom of the PPN cabinet. The cables are then run to the EPN cabinet
and up the outside of the rear panels to the desired carrier level.
Fiber Remoted Port Networks
For a standard reliability system with 1 fiber-remoted EPN, use 2 fiber optic
cables, 2 lightwave transceivers, and 2 lightguide interface units (provided by the
PSC).
