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.
