1  Insert a dry bulkhead swab into the bulkhead and rotate the swab several times.
2  Remove the swab and discard. 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 the swab and discard. Swabs may be used only once.
d Check with a fiber connector scope again to confirm that there is no dirt or

alcohol residue on the optical surface.

e If any alcohol residue remains, clean it off with a new dry bulkhead swab.

4 Mate all connectors to bulkheads and proceed to Verifying Equipment

Operation below.

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, i.e., fails verification or

indicates a reflection problem, clean the connectors and bulkheads again.
