Maintaining Fiber-Optic Cables In An Acx6160 - Juniper ACX6160 Hardware Manual

3. Insert the cable connector into the optical transceiver.
4. Secure the cable so that it does not support its 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. Bending
the cables beyond their minimum bend radius can damage the cables and cause
problems that are difficult to diagnose.
CAUTION: 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.

Maintaining Fiber-Optic Cables in an ACX6160

To maintain fiber-optic cables in an ACX6160:
• When you unplug fiber-optic cables from transceivers, place rubber safety caps over the transceivers
and on the end of the cables.
• Anchor fiber-optic cables to avoid 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.
• Do not bend fiber-optic cables beyond their minimum bend radius. Bending the cables beyond their
minimum bend radius 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. Attach a short fiber extension to the optical
equipment. Any wear and tear due to frequent plugging and unplugging is then absorbed by the
short fiber extension, which is easier and less expensive to replace than the instruments.
• Keep fiber-optic cable connections clean. Microdeposits of oil and dust in the canal of the transceiver
or cable connector can cause loss of light, reduction in signal power, and possibly intermittent
problems with the optical connection.
To clean the transceiver canal, use an appropriate fiber-cleaning device such as RIFOCS Fiber Optic
Adaptor Cleaning Wands (part number 946). Follow the directions in the cleaning kit you use.
