Cleaning & Inspection
Cleaning and visual inspection of a termini endface is part of the good practices for fiber 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 fiber optic video probe (magnification 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 figure below).
2 Cleaning
A- Use a lint free tip moistened with 99% reagent grade isopropyl alcohol or optical quality cleaning fluid 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 fiber optic video probe (Magnification 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 identified then clean (see below).
E.g. Magnification X 400 of two multimode fibers
For more details, please refer to the acceptance criteria and cleaning procedures defined by IEC for multimode or
singlemode connector termini endface
