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.
Maintain the Fiber-Optic Cables in a Router
To maintain 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 cable 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 the cable is not supporting 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. Microscopic deposits 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.
After cleaning the transceiver, make sure that the connector tip of the fiber-optic cable is clean. Use
only an approved alcohol-free fiber-optic cable cleaning kit such as the Cletop-S
®
Fiber Cleaner. Follow
the directions in the cleaning kit you use.
