Cleaning OBIS and Sapphire Fiber Tips
Page 4 of 8
Fiber Tip
Inspection
Technique
The inspection of the fiber tip is done with either a desktop video
fiberscope or a handheld fiberscope. Both tools are customized
microscopes used for inspecting optical fibers. The scope should
provide at least 200x total magnification. A specific adapter is
needed for the FC/APC (Fiber Connector/Angle Physical Contact)
to properly inspect the fiber tip.
To inspect the connector:
1. Make sure that the laser is turned off before you begin the
inspection.
2. Put the appropriate inspection adapter or probe on your equip-
ment.
3. Unscrew/remove the dust cap.
4. Insert the fiber connector into the fiberscope adapter and adjust
the focus ring so that you see a clear fiber tip image.
5. Clean the fiber tip and re-inspect, as necessary. Refer to the
“General Cleaning Process” (p. 3) for an overview on fiber tip
cleaning.
6. Immediately plug the clean connector into the mating clean
connector to reduce the risk of re-contamination.
