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. Select the dustfree absorbent swab with a proper diameter based on the type
of an adapter.
For SC and FC ber adapters, use the dustfree absorbent swab with a diameter of 2.5
mm (0.1 in.); for the LC ber adapter, use the dustfree absorbent swab with a
diameter of 1.25 mm (0.05 in.). See Figure 4-249 and Figure 4-250.

4. Put a little cleaning solvent on the dustfree absorbent swab.
5. Place the dustfree absorbent swab gently on the adapter so that the cleaning
solvent is against the ber end face. Draw out the dustfree absorbent swab
from the ber adapter and then rotate the dustfree absorbent swab clockwise
once. Ensure that the tip of the dustfree absorbent swab directly contacts the
ber end face.
