Connect Fiber Optic Cables
NOTE:
Always use the Cable Running List that accompanies the system when
installing fiber optic cables. The following procedure is a
typical
example of
how to cable a system.
If the cabinets are close together, the signal may go through a single, directly-
connected fiber optic cable. If the cabinets are far apart, it may be easier to
connect the cabinets through an LIU or fiber shelf.
For each fiber indicated in the fiber optic Cable Running List:
1. Install a lightwave transceiver on the cabinet connector at the position in
the FROM column in the running list.
2. Select a cable indicated by the CABLE CODE and LENGTH in the running
list. Connect 1 of the fibers to each connector on the lightwave
transceivers just installed. The fiber is numbered 1 or 2. The connector on
the transceiver is labeled TX or RX. Keep track of which fiber connects to
which transceiver connector. Label both ends of these cables.
3. Route the fiber optic cables from the transceiver out of the cabinet. Secure
the cables to the cable-tie rack. Keep the fiber optic cables clear of the
heavier I/O cables.
4. If the cabinet in the TO column in the running list is located remotely from
the FROM cabinet, connect to the TO cabinet by way of the LIU.
5. Install a lightwave transceiver on the cabinet connector at the position in
the TO column in the running list.
6. Route the cables from the FROM cabinet down into the cable trays of each
EPN cabinet. Connect the cables to the lightwave transceiver just installed
on the TO cabinet.
7. Connect the fiber that comes from the TX connector of the FROM
transceiver to the RX connector of the TO transceiver and vice versa.
8. Route the cables through the cabinet and through cable organizers as
provided. Secure the cables to the cable-tie rack.
