- Two types of latches on fiber optic connectors:
• LC/PC connector, opened by pressing the buckle, as shown in Figure 14.
• MPO connector, opening automatically when the buckle is pulled, as shown in Figure 15.
Procedure:
1. Wear an ESD wrist strap or ESD gloves. When wearing an ESD wrist strap, ensure that the ESD wrist strap
is in close contact with your wrist, and insert the other end into the ESD jack of the device or cabinet/rack.
2. Before replacing an optical module, determine in which cabinet and chassis the optical module is installed,
find the optical module in the chassis, and attach a label to the optical module. Record optical fiber
locations on the optical module to be replaced and check whether the labels on the optical fibers are
correct and clear. If any label is unclear, make and attach a new label to the optical fiber to ensure correct
connection.
3. Rotate the handle of the optical module down, gently push the optical module, and then pull out the
optical module by the handle. Remove the optical fibers from the optical module and cover them with dust
caps.
