6.3 Care of Fiber-optic Connectors
Damage to optical connectors account for more than 70 percent of
equipment performance degradation. To avoid such damage, the user
should use only industrial grade 99% pure isopropyl alcohol and follow
the procedures below to keep the connectors, adaptors and receptacles
clean.
Cleaning Optical Connector End-face with Wipe and Alcohol
To properly clean optical connectors utilizing lens tissue grade wipes and alcohol
follow the procedure below. The moist wipe removes dust particles, oil and
contaminants that may damage or blot the end-face of the connector during
connection. The dry wipe removes residual alcohol that may be ignited by optical
emission.
1. Disable the optical output and turn off unit to prevent accidental exposure or
damage to the optical connector by optical emission.
2. Moisten a wipe with alcohol by placing on top of the alcohol dispenser and
push down to saturate the wipe.
3. Place the moist wipe on a work surface, and place a second dry wipe next to
it.
4. Wipe the optical connector, end-face down on the moist wipe 3 times and
then repeat on the dry wipe.
5. Visually inspect the end-face of the optical connector with an optical
microscope to verify cleanliness. Repeat steps 2 to 5 as needed.
Cleaning Optical Connector Sides, Receptacles, Adaptors with Swab and
Alcohol
Dust or particles can adhere to the insides of receptacles and adaptors or the sides
of the optical connector ferrule. Their presence can affect the alignment of the optical
fiber connectors and increase connection loss. To properly clean optical connectors,
receptacles, and adaptors utilizing a swab and alcohol follow the procedure below:
1. Disable the optical output and turn off unit to prevent accidental exposure or
damage to the optical connector by optical emission.
2. Moisten the swab by placing it on top of the alcohol dispenser and push down
to saturate the swab.
3. For receptacles, adapters, or other connection points, insert the moistened
swab and rotate the tip 1/2 turn clockwise and counter-clockwise 6 times
while applying light but firm pressure.
4. For fiber connectors, rotate the tip of the moistened swab 5 revolutions
around the connector while applying light but firm pressure.
5. Visually inspect the end face of the connector with an optical microscope to
verify cleanliness. Clean end-face as needed.
