Connect A Fiber-Optic Cable; How To Handle Fiber-Optic Cables - Juniper QFX10002 Hardware Manual

Connect a Fiber-Optic Cable

Before you connect a fiber-optic cable to an optical transceiver installed in a device, ensure that you
have taken the necessary precautions for safe handling of lasers (see
and Warnings
).
To connect a fiber-optic cable to an optical transceiver installed in a device:
LASER 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
Figure 53: Connect a Fiber-Optic Cable to an Optical Transceiver Installed in a Device
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.

How to Handle Fiber-Optic Cables

Fiber-optic cables connect to optical transceivers that are installed in Juniper Networks devices.
