Background Information

Be careful： 
During the replacement of the optical module, do not look directly at the fiber interface to avoid laser damage to the eyes.
note： 

• The optical module of the non-certified optical module cannot be guaranteed. This may result in unstable services. Huawei will not be responsible for the problems caused by non-Huawei switch authentication optical modules, and will not solve them in principle.
• Care must be taken during fiber insertion and removal, taking care not to damage the fiber head.
• The optical module is a static-sensitive component. Anti-static measures should be taken during the entire operation to avoid damage to the optical module.
• The optical module cannot be inserted in the reverse direction. If the optical module cannot be inserted into the bottom in one direction, it cannot be pushed hard inside. The optical module is flipped 180 degrees and then reinserted.

·     Anti-static wrist strap or anti-static gloves

·     Fiber dust cap

·     Optical module dust plug

·     alcohol cotton

1.Wear an antistatic wrist strap or antistatic gloves. If you wear an antistatic wrist strap, make sure that one end of the ESD wrist strap is grounded and the other end is in good contact with the wearer's skin.

2. Record the location of the cables on the optical modules to be replaced, and check whether the labels on the cables are correct, clear, and clean. If the label is not easy to identify, you need to re-make and paste the label to avoid errors when connecting the cable.

3. Open the buckle on the fiber interface, then push the fiber connector into the connector and pull it out. Finally, wear a dust cap on the fiber connector.

· One is the LC/PC connector, which needs to be pressed to open, as shown in Figure 1.

· One is an MPO connector that automatically opens during the process of pulling the buckle, as shown in Figure 2.

· One is the SC/PC connector, which automatically opens during the process of pulling the buckle, as shown in Figure 3.

1 4. Pull out the optical module, plug the dust plug and dispose of it properly.

There are two types of snaps on the optical module. A pull-type handle that requires a flip handle to open, as shown in Figure 4. The other is a handle-type handle that automatically opens during the process of pulling the handle, as shown in Figure 5.

5、Remove the new optical module from the package and slowly insert it into the connector until you hear a “click” to indicate that it is installed.

Description: 

To ensure successful docking, the new optical module must match the optical parameters of the optical module at its opposite end.

6. Locate the fiber to be connected, find the interface corresponding to the fiber through the label on the fiber, remove the dust cap and connect the fiber to the interface.

Description: 

If the docking is unsuccessful, wipe the end face of the fiber connector in one direction with alcohol cotton and try to dock.

Follow-up treatment:

If the new optical module does not work properly after replacement, contact your device dealer and local maintenance personnel for technical support.
