User’s Manual for ION-U 7/8/85/17/19
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.
Note:
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.
When you clean fiber components, always complete the following steps carefully:
1. Turn off the ION-U system (laser sources) before you inspect fiber connectors.
Never look into a fiber while the system lasers are on!
2. Check the connectors or adapters with a fiberscope before cleaning.
3. If the connector is dirty, clean it with a lint-free wipe (dry cleaning).
4. Inspect the connector.
5. If the connector is still dirty, repeat the dry cleaning technique.
6. Inspect the connector.
7. If the connector is still dirty, clean it with 99% isopropyl alcohol (wet cleaning)
followed immediately with a dry clean in order to ensure no residue is left on
the endface.
8. Repeat steps 5 through 7 until endface is clean.
