Frequent plugging and unplugging of fiber-optic cable into and out of optical
instruments, such as ATM or SONET/SDH analyzers, 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 have cleaned the transceiver on the fiber-optic PIC, 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
directions for the cleaning kit you use.
Check the LEDs on PIC faceplates. The meaning of the LED states differs for various
PICs. For more information, see the T1600 Core Router PIC Guide. If the FPC that houses
the PIC detects a PIC failure, the FPC generates an alarm message to be sent to the
Routing Engine.
