Fiber-System Installation:
Fiber-cable connectors have to be of the same type (LC/APC) as the connectors
used for the unit. The fiber-optic cables are connected to the optical transceiver.
Notice: Angled connectors are not compatible with straight optical connectors; non-
compatibility of connectors will result in permanent damage to both connectors.
Before connecting the fiber cables, follow the procedure below to ensure optimized
performance. It is important for these procedures to be carried out with care:
 Remove fiber-optic protective caps just before making the fiber connections.
Do not leave any LC/APC connectors open as they may attract dirt. Unused
optical connectors must always be covered by their caps.
 Do not bend the fiber-optic cable in a tight radius (< 5 cm) as this may cause
damage to the cable and interrupt transmission.
 Using high-grade alcohol and lint-free cotton cleaning swabs, clean the end of
the fiber-optic cable that will be inserted in the optical connectors on the donor
interface box. Use a fiber end-face inspection tool to scan both, the class fiber
and its surrounding area.
 Check for dirt on the cladding, chips/pits, dirt on the ferrule, and scratches.
 Connect the fiber-optic cables by inserting the cable end into the laser
receptacle.
 Do not use any index-matching gels or fluids of any kind in these connectors.
Gels are intended for laboratory use and attract dirt in the field.
Notice: Care should be taken when connecting and disconnecting fiber-optic cables -
use the connector housing to plug or unplug a fiber. Scratches and dust
significantly affect system performance and may permanently damage the
connector. Always use protective caps on fiber-optic connectors not in use.
Cleaning Procedure for Fiber-Optical Components:
Any contamination in the fiber connection results in additional optical transmission
loss which could cause whole system failure. It is thus recommended that every fiber
connector be inspected and cleaned prior to mating.
The goal is to eliminate any dust or contamination and to provide a clean
environment for the fiber-optic connection.
