extension to the optical equipment. The short fiber extension absorbs wear and tear due to frequent
plugging and unplugging, 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 instructions 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 Opptex Cletop-
S
®
Fiber Cleaner. Follow the instructions in the cleaning kit you use.
