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.
