Dry Cleaning Technique

The following procedure describes how to use a dry cleaning technique for fiber optics.
NOTE
In the following procedure, use lint-free swabs that resemble a q-tip in
appearance. These are only applicable to cleaning receptacles. Connector
cleaning requires a connector cleaner.

Required Tools

The following item is required to perform a dry cleaning technique:
■ Lint-free swabs, preferably clean room quality
The following describes a dry cleaning procedure using lint-free swabs:
1. Make sure the lasers are turned off before you begin the inspection.
2. Remove the protective endcap and save.
3. Inspector the conector with a fiberscope.
4. If the connector is dirty, clean it with a lint-free swab.
5. Lightly press and turn the swab to clean the ferrule face.
6. Properly dispose of the swab. Never reuse a swab.
7. Inspect the connector again with the fiberscope.
8. Repeat this process as necessary.
9. Replace protective endcap.

Wet Cleaning Technique

The following procedure describes how to use a wet cleaning technique for fiber optics.
NOTICE
Improper cleaning can cause damage to equipment. The primary concern
with the use of isopropyl alcohol is that it may not be removed completely
from the connector or adapter. Residual liquid alcohol acts as a transport
mechanism for loose dirt on the endface. If the alcohol is allowed to evaporate
slowly off the ferrule, it can leave residual material on the cladding and fiber
core. This is extremely difficult to clean off without another wet cleaning and
usually more difficult to remove than the original contaminant. Liquid
alcohol can also remain in small crevices or cavities where it can re-emerge
during fiber connection.
