Procedure
Step 1 Wear an ESD wrist strap or ESD gloves. Ensure that the ESD wrist strap is grounded and in a
close contact with your wrist.
Step 2 Record the location of each optical fiber on the old optical module and check whether the
labels on the optical fibers are correct and clear. If any labels are unclear, replace them and
ensure that the details are correct.
Step 3 Release the locking clip on the fiber connector, gently push the fiber connector inward, and
then pull out the optical fiber. After removing the optical fibers from the optical module,
cover the connectors with dust caps.
The locking clip varies on different fiber connectors.
