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. Micro-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 CleaningWands (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 Opptex Cletop-S
®
Fiber Cleaner. Follow the directions in the cleaning kit you
use.
