Cleaning and visual inspection of a termini endface is part of the good practices for fi ber optics.
This is necessary to ensure the good optical performances of an LC contact inside a UTS LC connector.
Please note that most of the standard inspection and cleaning tool on the market can be used for maintenance of an LC contact mounted in an 
UTS LC connector.

1 Inspection

A-  Use a fi ber optic video probe (magnifi cation X200 minimum) to inspect the termini endface for contamination,

chips, pits, scratches and shatters in the core and in the inner of the cladding (see fi gure below).

2 Cleaning

A-  Use a lint free tip moistened with 99% reagent grade isopropyl alcohol or optical quality cleaning fl uid to clean

the termini endface. Always wipe in one direction, not back and forth.

B-  Dry the termini endface with a dry tip.

C-  Re-inspect the termini endface with a fi ber optic video probe (Magnifi cation x200 minimum) and verify that

the contamination has been removed.

D- If the contamination is still present then repeat step A & B.

E-  If after repeated attempts, the contamination is still present and cannot be removed like minor scratches, chips

or pits then re-polish the optical contact (refer to the LC supplier instruction).

B-  If dirt, debris or other surface contamination is identifi ed then clean (see below).

E.g. Magnifi cation X 400 of two multimode fi bers
