Cleaning Procedure for Fiber-Optical Components:

Caution: Laser radiation. Risk of eye injury in operation. Do not stare into the

beam; do not view it directly or with optical instruments.

Any impurity 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.

When you clean fiber components, always complete the following steps carefully:

1. Turn off the ION system (laser sources) before you inspect fiber connectors.

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

end face.

8. Repeat steps 5 through 7 until end face is clean.

4.2.9. Protective Plug

A protective plug is provided for the connection of the fibre-optic cables. If the optical

connection is done without this kit, the RU no longer has the stated IP class. Dust,

humidity or water might ingress into the housing and damage the RU.
