Connector inspection
After cleaning the connector, inspect the ferrule endface to ensure that it is free from any
particulate contamination using an optical fiber inspection scope of at least 200X
magnification. When using an optical fiber scope (for example, the Noyes OFS 300-200X)
exercise extreme caution to assure fiber being examined is de-energized.

1
Follow the instructions in the manual provided with the Optical Fiber Scope to view the
ferrule endface of the fiber under inspection.
........................................................................................................................................................................................................................
2
The visual area of the ferrule endface (ferrule and fiber) as observed by the inspection
system/scope should be free of any contaminates. See
Figure B-3, “Acceptability Criteria
for Fiber Cleaning” (p. B-10) .
Repeat the Cleaning Procedure if the fiber endface does not meet the following
requirements:
Requirement: No fixed type of contamination (contaminates that remain at the same
location after three wet-dry cleaning cycles), regardless of size, is allowed in the
restricted area of the glass fiber endface.
Requirement: The restricted area is defined as ~66 microns (µm) diameter for both
singlemode and multimode fibers.
Requirement: No chips, cracks or scratches are allowed near the core of the glass
fiber endface.
Requirement: No large floating (loose) contaminates are allowed on the glass fiber
and ceramic ferrule endface.
WARNING
When using an optical power meter to verify the connector and fiber to be
clean, take special precaution to make sure the no power is being emitted from
the fiber before viewing.
