Memo：The water pipes are transparent pipes on the left and right respectively. Please
see the mark and then pass the water. The air pipe is in the middle of the two water pipes.
The default is a black pipe. Some of them will be transparent pipes. It will cause very
serious losses, please be careful not to connect wrongly.
Pay attention：5 steps to plug and unplug fiber
Step 1： Check whether the QBH connector and optical fiber plug are dirty,
and wipe it clean with alcohol and cotton swab (tissue paper) in time.
Memo： When inserting the optical fiber, the laser head needs to be placed
horizontally; ensure that the optical fiber is inserted horizontally
Step 2：QBH homing "two points and one line"
