How to use fiber inspection scope to inspect a fiber connector


To check the pin of a fiber optic connector with fiber inspection scope, the following tools are needed:
 
200 px or 400 px fiber inspection scope. (proper adapters should be selected according to the fiber optic connector for test)
Alcohol (100%)
Lens papers
Light source
Inspecting Processes
 
The main processes of using fiber inspection scope to inspect a fiber optic connector are listed as following:
 
1.Plug out the dust cap on one side of the fiber optic connector for testing.
 
2.Insert the fiber optic connector into the adapter of fiber inspection scope.
 
3.If you cannot see the fiber optic connector pin through fiber inspection scope, adjust the fiber inspection scope knob until the whole interface of the pin can be observed.
 
4.Change the focal length of the fiber inspection scope to adjust the image of the pin to the clearest.
 
5.Inspect the interface of the connector pin. For a clean and well polished fiber optic connector, the interface of the pin should be smooth round-shape and the cross surface of the fiber core and the pin should be in the same plane showing shape of concentric ring (shown in the following picture). If the interface is not clean, wipe the interface with lens paper that is dipped with alcohol until it is clean.

6.Remove the dust cap on the other side of the fiber optic connector. Then inject the light into the connector. If there is no light released from interface on the side which has just been inspected in the last step, there should be a fracture in this connector.
 
7. Inspect the unchecked side of the fiber optic connector following the above steps.
 
8.Label the fiber optic connector end which has problems and take the further process—re-polishing or reconnect the fiber optic connector. Then, repeat the above steps.

using fiber inspection scope to inspect a fiber connector can fast easy find the problems.the fiber optic components are clean is a requirement for maintaining quality connections between fiber optic equipment.
