NOTE:
Keep track of which fiber attaches 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 attaching to each connector are
numbered either "1" or "2." A viable fiber connection is only made when both
fibers in each cable ("1" and "2") route from the "TX" connector of a port
network to the "RX" connector of its adjacent port network. See
NOTE:
When finished, refer to
administer the fiber links.
Collocated Port Networks
For a high reliability system with 1 collocated expansion port network, use 1 fiber
optic cable and 2 lightwave transceivers to directly connect the networks.
For a high reliability system with 2 collocated expansion port networks, use 3 fiber
optic cables and 6 lightwave transceivers to directly connect the networks.
NOTE:
Based on floor plan considerations, the length of these fiber cables may
vary. 20 foot (6.1 m) cables are normally adequate for 2 port networks.
For collocated cabinets, the fiber optic cables should be routed directly from the
PPN to the EPN cabinet. If a "DEFINITY style" PPN cabinet is collocated with
another "DEFINITY style" EPN cabinet, the preferred routing is to run the cables
up the cable tray and out the top of the PPN cabinet. The cables are then run to
the other cabinet, through the top of the cabinet, and down the cable tray to the
desired carrier level.
NOTE:
Refer to Installation and Test for Multicarrier Cabinets (MCC1) in the Made
Easy tool for additional guidelines about fiber routing.
If a "DEFINITY style" PPN cabinet is collocated with either a small cabinet,
medium cabinet, or single-carrier cabinet 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.
