Connect a Fiber-Opc Cable
Before you connect a ber-opc cable to an opcal transceiver installed in a device, ensure that you
have taken the necessary precauons for safe handling of lasers (see Laser and LED Safety Guidelines
and Warnings ).
To connect a ber-opc cable to an opcal transceiver installed in a device:
LASER WARNING: Do not look directly into a ber-opc transceiver or into the ends of
ber-opc cables. Fiber-opc transceivers and ber-opc cables connected to
transceivers emit laser light that can damage your eyes.
1. If the ber-opc cable connector is covered with a rubber safety cap, remove the cap. Save the cap.
2. Remove the rubber safety cap from the opcal transceiver. Save the cap.
3. Insert the cable connector into the opcal transceiver (see Figure 46 on page 112).

4. Secure the cables so that they do not support their own weight. Place excess cable out of the way in
a neatly coiled loop. Placing fasteners on a loop helps cables maintain their shape.
CAUTION: Do not bend ber-opc cables beyond their minimum bend radius. An arc
smaller than a few inches in diameter can damage the cables and cause problems that
are dicult to diagnose.
Do not let ber-opc cables hang free from the connector. Do not allow fastened
loops of cables to dangle, which stresses the cables at the fastening point.
