WARNING:



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.

1 Insert a dry bulkhead swab into the bulkhead and rotate the swab several times.
2 Remove and discard the swab.

Important: Swabs may be used only once.

3 Check the bulkhead optical surface with a fiber connector scope to confirm that it

is clean. If further cleaning is needed:
a Moisten a new bulkhead swab using a lint-free wipe moistened with optical

grade (99%) isopropyl alcohol.

b With the connector removed, fully insert the bulkhead swab into the

bulkhead and rotate the swab several times.

c Remove and discard the swab.
d Repeat steps 1 and 2 with a new dry bulkhead swab to remove any excess

alcohol or residue.

e Check with a fiber connector scope again to confirm that there is no dirt or

alcohol residue on the optical surface.

f If any alcohol residue remains, repeat steps 3d-3f.

4 Mate all connectors to bulkheads and proceed to Verifying Equipment

Operation.

5 It is also recommended that all connectors be visually inspected after cleaning to

verify the connector is clean and undamaged.

Verifying Equipment Operation

Perform circuit turn-up. If the equipment does not come up, it means the verification
is failed or indicates a reflection problem, clean the connectors and bulkheads again.
