3. Insert the cable connector into the optical transceiver (see Figure 197 on page 348 ).

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.
Follow these guidelines when handling fiber-optic cables:
• When you unplug a fiber-optic cable from a transceiver, place rubber safety caps over the transceiver
and on the end of the cable.
• Anchor fiber-optic cables to prevent stress on the connectors. When attaching a fiber-optic cable to
a transceiver, be sure to secure the fiber-optic cable so that it does not support its own weight as it
hangs to the floor. Never let a fiber-optic cable hang free from the connector.
• Avoid bending fiber-optic cables beyond their minimum bend radius. Bending fiber-optic cables into
arcs smaller than a few inches in diameter can damage the cables and cause problems that are
difficult to diagnose.
• Frequent plugging and unplugging of fiber-optic cables in and out of optical instruments can damage
the instruments, which are expensive to repair. To prevent damage from overuse, attach a short fiber
