[0031] A first optical fiber collimator 1, a second optical fiber collimator 2, a connecting rod 3, a control system and a laser emitting device.

[0032] The first fiber collimator 1 is connected to the first optical device 10 and the light source 9 in sequence to level the optical fiber input to the first optical device; the second fiber collimator 2 is connected to the second optical device 11 and the power meter 12 in sequence. The first fiber collimator 1 and the second fiber collimator 2 are fixed by a connecting rod 5. Both ends of the connecting rod 5 are provided with a fixing ring for fixing the fiber collimator. The control system includes a sliding block 6, a fixing groove 7 and a friction block 8. The sliding block 6 is provided with a plurality of connection ports, and the sliding block 6 is arranged on the connecting rod 5 through the connection ports. The sliding block 6 is located on the outside of the fixing ring. The laser emitting device: includes a laser pen 4 and a control switch 3 for controlling the laser pen. The laser pen 4 is located between the first fiber collimator 1 and the second fiber collimator 2. The control switch includes a power switch 3-1, a band adjustment switch 3-2, an optical power adjustment switch 3-3 and two standby switches 3-4.

[0034] The specific implementation process is as follows:

[0035] Start the light source 9 of the device. After the light source 9 is started, start all the devices inside the device, turn on the band adjustment switch 3-2, and adjust the band of the optical fiber according to the optical fiber model, such as: 1310, 1550 band, etc. Each knob is adjusted to the corresponding band. The first end of the first optical device 10 is connected to the light source 9, and the pigtail at one end of the first optical device 10 is inserted into the first optical fiber collimator 1. Use another optical fiber with the same band (provided by the second optical device 11) to insert one end into the second collimator 2, and the second end of the second optical device 11 is connected to the optical power meter 12. Check whether the red light beam of the laser pen 4 propagates in the optical fiber.
