(connectors with green boots) to make sure the full surface contacts the
cloth. You will need to tilt the connector slightly. Using an automatic cleaner
is our preferred technique. Note that some low cost cleaners may leave small
particles on the fiber surface.
Or:
Moisten a clean optical wipe with alcohol and wipe connector. Finish by
wiping the connector with a dry part of the wipe. Be careful not to allow oil
from fingers to contact connector. Allow the connector to dry for 1 minute.
Inadequate drying can result in the alcohol residue burning into the
connector end when the fiber is lit.
Inspect the connector ferule under the microscope. Clean again if necessary.
If a connector is to be used to transmit high powers (
＞
50mW), great care
should be taken in cleaning. Mating of these connectors should be kept to a
minimum.
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.
Trouble shooting
Q:
A small black area appears in the middle of the connector which cannot be
remove by cleaning.
A:
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 for assistance.
Q:
A small circle of dried droplets are visible on the end of the connector.
A:
The connectors were mated when they are still wet (typically from
water/alcohol). Repeat cleaning procedure.
Q:
The connector is clean but the loss on mating varies by 10dB or more.
A:
Check to see if the bulkhead adapter sleeve is cracked. Be careful not to
over-tighten connectors.
Q:
A gray powdery grime continues to appear on the connectors after
