Bulkhead cleaning
Fiber bulkhead adapters contain a zirconia or phosphor-bronze sleeve. After removing the
connectors, these can be cleaned with a pipe cleaner moistened with isopropyl alcohol,
and dried with canned air.
Troubleshooting
A small black area appears in the middle of the connector which cannot be removed by
cleaning.
Some material (typically oil from skin contact, residue alcohol or particles from connector
cleaning devices) has burnt on the connector surface. Do not use your device and contract
OT for assistance.
A small circle of dried droplets are visible on the end of the connector.
The connectors were mated when one was still wet (typically from water/alcohol). Repeat
cleaning procedure.
The connector is clean but the loss on mating varies by 10dB or more.
Check to see if the bulkhead adapter sleeve is cracked. Be careful not to over-tighten con-
nectors.
A gray powdery grime continues to appear on the connectors after repeated mating.
If the bulkhead adapter sleeve is made from phosphor-bronze, some of the metal is
probably rubbing off on the connectors.
