Cleaning Connectors
It is important that all external jumper connectors be cleaned before inserting them
into the optical module. Follow these steps to clean fiber optic connectors that will be
connected to the optical module:
Important: Before you begin, remove optical power from the module or ensure that
optical power has been removed.
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
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
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
Note: It is generally more difficult to clean bulkhead connectors and verify their
condition due to limited accessibility of the fiber end face. For this reason, even on
products with accessible bulkhead connectors, you should only attempt to clean a
bulkhead connector when a dirty connector is indicated.
Follow these steps to clean the bulkhead:
Avoid personal injury! Use of controls, adjustments, or performance of
procedures other than those specified herein may result in hazardous
radiation exposure.
Avoid personal injury! The laser light source on this equipment emits
invisible laser radiation. Avoid direct exposure to the laser light source.
Avoid personal injury! Viewing the laser output with optical instruments
(such as eye loupes, magnifiers, or microscopes) may pose an eye hazard.
