Step Action
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 contaminants (see
Figure C-1 on page C-11).
Requirement: No fixed type of contamination (contaminants which after
3 wet-dry cleaning operations remain at the same location on the
connector endface), regardless of size, is allowed in the restricted area of
the glass fiber endface as determined after 3 successive wet-dry cleaning
attempts. The restricted area is defined as ~66 micron (um) diameter for
both single-mode and multimode fibers. Chips, cracks, and scratches are
not allowed near the core of the glass fiber endface. No large floating
(loose) contaminants are allowed on the glass fiber and ceramic ferrule
endface. If after 3 successive wet-dry cleaning attempts, particulate that
is less than 8 um in size remains fixed on the ceramic ferrule endface and
outside the defined restricted area on the fiber glass endface, it will be
acceptable.
