Problem Description
Optical module Operation guide
solution
Step One: During the production of optical modules, there is a cage fixture similar to the one used by customers when inserting equipment, as shown below: (We fix the cage on Mon metal base to facilitate module insertion and removal)

**Step Two:**Insert the module into the cage Medium lock it: insert the module straight into the cage with the gold finger end facing the cage. (Pay attention to the positive and negative directions of the module. If the directions are wrong, Yes inserted properly. After locking, the module Yes be stuck Auto unlock after cage.)

Step Three: Pull the module out of the cage and unlock it: first pull out the optical fiber from the optical port of the module, then turn the Unlock handle to 90 degrees (at this time the protrusion on the Unlock drops to Lowest), and then pinch the handle to pull the module out of the cage. (You don’t need to use too much force. If you still can’t pull it out, OK whether the module is stuck somewhere inside the cage.)
