[0025] Working principle:

[0026] Installation Phase

[0027] First, manually push the clamp rod 301, and the clamp rod 301 drives the limit block 302 to move to both ends of the connecting seat 303. At the same time, the limit block 302 will pull the tension spring 306 to lengthen the length, and place the shell 1 on the surface of the connecting seat 303. After loosening the clamp rod 301, the tension spring 306 will pull the clamp rod 301 on the limit block 302 to fit and tighten the shell 1 and the side cover 402. According to the needs, choose clamp blocks 305 of different lengths, turn the fixing bolts 304 to connect the clamp block 305 and the clamp rod 301, so that the outer wall of the clamp block 305 can be clamped in the installation position, or it can be directly connected to the installation position through the holes on the surface of the connecting seat 303.

[0028] Working stage

[0029] A connector 404 is used to connect the single-mode conical lens optical fiber 12 and the high-power semiconductor optical amplifier 13 to the outside, so that the double-section integrated conical amplification structure of the electrode improves the saturated output power and gain while ensuring the single-mode output of the amplifier. The saturated output power can be increased to the watt level. Through the single-mode conical lens optical fiber, fast-axis collimator, slow-axis collimator, and focusing lens inside the high-power semiconductor optical amplifier 13, high-efficiency coupling with the single-mode optical fiber can be achieved under the conditions of high saturated output power and high gain.

[0030] Disassembly phase

[0031] Manually twist the fixing head 405 to separate the fixing head 405 from the threaded block 403, so that the fixing seat 406 and the connecting head 404 are separated from the side cover 402, and the side cover 402 can be manually buckled again to separate the side cover 402 from the outer shell 1. Manually pulling out the side cover 402 drives the pull-out seat 401 to separate from the outer shell 1, so that the surface of the pull-out seat 401 is exposed, thereby achieving the effect of cleaning and maintenance of the interior.
