Problems solved by technology

[0002] At present, optical fiber communication has achieved large-scale coverage, especially the popularization of FTTH fiber-to-the-home. People's dependence on the network is increasing day by day. However, the supervision of optical fiber network construction is not in place, resulting in poor quality of optical fiber network construction. The acceptance of construction projects can only be opened or not. It is impossible to accurately judge the loss and cracking of each segment of fiber and each node in the fiber optic line, which seriously affects the user's experience of the fiber optic network. Operators need to spend more money on network maintenance. Users also have to bear the economic losses caused by disconnection

[0003] The products currently available on the market to detect fiber line loss and fiber end face loss are optical time domain reflectometers, which use the reflection loss phenomenon of light waves at the fiber loss point and the coupling point of the fiber connector to launch the detection light wave in the fiber line , by detecting the light wave returned from the original path, the distance between the loss point and the coupling point and the reflected light wave intensity at this point are measured, so as to indirectly judge the connection loss and the total line loss of the loss point and the coupling point. The loss point and coupling point on the line, and the optical fiber line are tested in high speed and in batches, and the fault point can be accurately located. However, due to the high price of the equipment, the price exceeds tens of thousands of yuan, and it cannot be equipped in large quantities to ordinary construction personnel. The difficulty has brought about the fact that this equipment is rarely used in engineering construction. The key is that it is impossible to upload the test data and on-site port number information to the cloud server to form a complete optical fiber line routing topology map and provide operators with optical fiber node loss and loss information. Complete information such as the amount of change, which is also the main problem to be solved by the patent of the present invention
