Fiber Connector Cleaning: Inspect, Clean, and Reinspect Log
The purpose of fiber connector cleaning is not to wipe it randomly, but to examine the end surface with appropriate equipment, clean it with the appropriate method if necessary, and check it again. A clean-looking outer body does not indicate that the optical contact surface is clean. Connection and test cables should be evaluated together; The live fiber end should not be looked at.
Check both sides of the pair to be connected
Leviton's cleaning instructions address the mating pair of connections, not just the patch cable end. The adapter, cassette port and test jumper may also be included in the scope of control. The probe and cleaning tool used must be suitable for the connector type. Follow the product instructions to avoid further contaminating the surface with an inappropriate cloth or method.
New packaging does not remove the need for inspection. A clean connector can become contaminated when mated with a dirty port. Protective caps are part of storage, not a substitute for inspection before testing. Repeated wiping alone must not be used to declare a suspected damaged component acceptable.
How should maintenance work be recorded?
| control | Information to be recorded | decision |
|---|---|---|
| ID | Link ID, connector end and connector type | Match with tag |
| first review | Clean, dirty or suspected damaged | Add images and description |
| Work performed | Tool, method and person performing the check | Check compliance with product instructions |
| final check | Re-examination and measurement record | Connect or disconnect depending on the result |
The states in the table are sample workflow fields; It does not replace IEC acceptance limits. If it is not clear which end the image belongs to, the recording cannot be used during maintenance. Use the end and line number together to avoid confusing different fibers with the same name.
Cleanliness and performance measurement are different proofs
Even if the visual control is successful, the application loss budget of the line should be verified separately. If loss is high, don't focus solely on connector dirt; The test setup, connections, and physical condition of the cable should also be examined. Include in the maintenance plan that the control loop may be required again when the connection is disconnected and reconnected.
