Tools, Equipment, and Materials
The following lists the required tools, equipment and materials for cleaning optical
ber connectors:
● cassette cleaner
● Optical power meter
● 400X
ber microscope (A video ber microscope is recommended.)
Precautions
Laser energy is invisible and may cause eye injuries. Never look directly into ber
connectors or ports.
Electrostatic discharge is hazardous to the electronic equipment. Wear an ESD
wrist strap and ensure that the strap is grounded properly before touching the
equipment and boards, to protect the static-sensitive components against
electrostatic discharge of the human body. Otherwise, the equipment may be
damaged or the service may be interrupted.
Procedure
1. Shut down the laser and disconnect the ber end before inspecting the ber
connector.
2. Test the optical power using a power meter to ensure that the laser is shut
down.
3. Press down and hold the lever of the cassette cleaner. The shutter slides back
and exposes a new cleaning area. See Figure 4-47.
