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. Put a little cleaning solvent on the lens tissue.
4. Clean the
ber end face on the lens tissue. See Figure 4-50 and Figure 4-51.
Drag the ber end face on the same area in the lens tissue only once.
Otherwise, the connector can be contaminated or damaged.
