Fiber-Optic Cable Installation
Caution Do not user fiber loopbacks with the OC192 LR 1550 card unless you are using a 20 dB attentuator.
Never connect a direct fiber loopback. Using fiber loopbacks causes irreparable damage to the
OC-192 card.
Procedure: Install Fiber-Optic Cables on OC-N Cards
Note Clean all fiber connectors thoroughly. Dust particles can degrade performance. Put caps on
any fiber connectors that are not used.
Step 1 Place the SC connector in front of the connection point on the card faceplate. Each card supports at least
one transmit and one receive connector to create an optical carrier port. Figure 1-31 shows the cable
location.

Step 2
Align the keyed ridge of the cable connector with the receiving slot on the faceplate connection point.
Step 3 Gently push the cable connector into the faceplate connection point until the connector snaps into place.
Procedure: Install the Fiber Boot
Cisco provides clear plastic fiber boots for the OC-3, OC-12, and OC-48 (except OC48 AS) cards. The
boots prevent hanging fibers from bending too sharply, which may degrade performance. The boots also
prevent the front door from interfering with hanging fibers. The fiber boots are not necessary for the
OC-192 and the OC-48 AS cards because of the angled SC connector. Figure 1-32 shows the fiber boot
attachment.
You can install the fiber boots on the fiber-optic cables before or after the fibers are attached to the optic
card.
