Maintaining Mx-Spc3 Services Card - Juniper MX960 Hardware Manual

The following guidelines apply specifically to fiber-optic cables:
When you unplug a fiber-optic cable, always place a rubber safety plug over the transceiver on the
faceplate and on the end of the cable.
Anchor fiber-optic cables to avoid stress on the connectors. Be sure to secure fiber-optic cables so that
they do not support their own weight as they hang to the floor. Never let fiber-optic cable hang free
from the connector.
Avoid bending fiber-optic cable beyond its bend radius. An arc smaller than a few inches can damage
the cable and cause problems that are difficult to diagnose.
Frequent plugging and unplugging of fiber-optic cable into and out of optical instruments can cause
damage to the instruments that is expensive to repair. Instead, 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 easy and inexpensive to replace.
Keep fiber-optic cable connections clean. Small microdeposits of oil and dust in the canal of the transceiver
or cable connector could cause loss of light, reducing signal power and possibly causing intermittent
problems with the optical connection.
To clean the transceivers, use an appropriate fiber-cleaning device, such as RIFOCS Fiber Optic Adaptor
Cleaning Wands (part number 946). Follow the directions for the cleaning kit you use.
After you clean an optical 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 Opptex Cletop-S Fiber
Cleaner. Follow the directions for the cleaning kit you use.
