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 arcsmallerthan a fewinches in diameter candamage 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 from a Device
Juniper Networks devices have field-replaceable unit (FRU) optical transceivers to which
you can connect fiber-optic cables.
Before you begin disconnecting a fiber-optic cable from an optical transceiver, ensure
that you have taken the necessary precautions for safe handling of lasers. See “Laser
and LED Safety Guidelines and Warnings” on page 241.
Ensure that you have the following parts and tools available:
•
A rubber safety cap to cover the transceiver
•
A rubber safety cap to cover the fiber-optic cable connector
