Cleaning Optical Connectors
WARNING:
Avoid damage to your eyes! Do not look into any optical connector while the
system is active. Even if the unit is off, there may still be hazardous optical
levels present.
Important: Read the above warning before performing cleaning procedures.
Cleaning Connectors
Important:
Important:
All external jumper connectors must be cleaned before inserting them into the
optical module.
Before you begin, remove optical power from the module or ensure that optical
power has been removed.
Complete the following steps to clean fiber-optic connectors that will be connected to
the optical module.
1 Inspect the connector through an optical connector scope. If the connector is
1 Inspect the connector through an optical connector scope. If the connector is
damaged, e.g., scratched, burned, etc., replace the jumper.
2 If the connector is dirty but otherwise undamaged, clean the connector as
follows:
a Make several swipes across the face of the connector with the appropriate
a Make several swipes across the face of the connector with the appropriate
ferrule cleaner. This will remove dust and some films.
b Listen for a slight "squeak" typically generated during this process, indicating
a clean connector.
c Inspect the connector again through the scope to confirm that it is clean.
3 If a second inspection indicates that further cleaning is needed:
a Use 99% isopropyl alcohol and a lint-free wipe to clean the connector.
b Use the appropriate ferrule cleaner again to remove any film left over from
b Use the appropriate ferrule cleaner again to remove any film left over from
the alcohol.
c Inspect the connector again through the scope and confirm that it is clean.
4 If necessary, repeat steps 3a-3c until the connector is clean.
Cleaning Bulkheads
Important:
Important:
Do not detach the bulkhead from the module front panel for cleaning under any
circumstances. There is little or no slack in the fiber attached to the bulkhead,
and any attempt to remove the bulkhead will risk damage to the fiber.
It is generally more difficult to clean bulkhead connectors and verify their
condition due to the inaccessibility of the fiber end face. For this reason, you
should only attempt to clean a bulkhead connector when a dirty connector is
indicated.
