4.2.4.5.6 Cleaning Optical Fiber Connectors Using the Cassette Cleaner
This topic describes how to clean the fiber connectors using a cassette cleaner.
Prerequisites
Before cleaning, inspect the fiber end face with a fiber microscope or a magnifier
to confirm the degree of fiber contamination. Clean the fiber only when it is
severely contaminated. This is because the cleaning operation itself may introduce
dust, dirt, or cause damage to the fiber.
The following procedure provides the steps to clean the fiber connectors using
cartridge type cleaners.
Tools, Equipment, and Materials
The following lists the required tools, equipment and materials for cleaning optical
fiber connectors:

Precautions
Laser energy is invisible and may cause eye injuries. Never look directly into fiber
connectors or ports.

reports alarms. Check whether the distance is consistent with that in the
previous test. If not, continue to test other ports.
After the abnormal port is found, test the port using a fiber microscope. If the
port is dirty, clean it. For details, see "Inspecting and Cleaning Optical Fiber
Connectors and Adapters".
After the port is cleaned, restore the port, and ensure that the connector is
tightened. Perform an OTDR test on the port to check whether loss and
reflection of each link and node are normal.
If the fault persists, replace the flange and perform an OTDR test on the port
that reports alarms to check whether loss and reflection of each link and
node are normal.
If the fault persists, replace the optical fiber and perform an OTDR test on the
port that reports alarms to check whether loss and reflection of each link and
node are normal.
If multiple abnormal points exist on the link, repeat steps
