To connect a fiber-optic cable to an optical transceiver installed in a device:
WARNING:
Do not look directly into a fiber-optic transceiver or into the ends of
fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to transceivers
emit laser light that can damage your eyes.
1. If the fiber-optic cable connector is covered with a rubber safety cap, remove the cap. Save the cap.
2. Remove the rubber safety cap from the optical transceiver. Save the cap.
3. Insert the cable connector into the optical transceiver (see
).

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 fiber-optic cables beyond their minimum bend radius. An
arc smaller than a few inches in diameter can damage the cables and cause problems
that are difficult to diagnose.
Do not let fiber-optic cables hang free from the connector. Do not allow fastened
loops of cables to dangle, which stresses the cables at the fastening point.
Disconnecting a Fiber-Optic Cable
Juniper Networks devices have field-replaceable unit (FRU) optical transceivers to which you can connect
fiber-optic cables.
