10. A network room optical fiber line transmission method, based on a network room optical fiber line transmission system according to any one of claims 1 to 9, Features: The specific steps are as follows: S1, converting electrical signals into optical signals, that is, realizing electro-optical conversion. The electrical signal modulates the light source through the driving circuit to generate an optical signal with information, and couples it into the optical fiber for transmission. An optical repeater is set at a certain distance to amplify the optical signal, compensate for the attenuation of the optical signal, and restore the received optical signal to an electrical signal and send it to the receiving end, that is, realizing photoelectric conversion. Then, the weak electrical signal is amplified to a sufficient level by the amplifier circuit; S2, OPM optical power module (22) completes real-time monitoring of optical fiber optical power. Once an optical power abnormality is found, the OTDR is immediately triggered to start the fault location test. The monitoring light and the service light are optically coupled through the WDM combiner module (23) to achieve the need of monitoring the optical fiber without interrupting the service. The TF filter module (24) prevents the test optical signal from affecting the normal communication of the service. The SOSM stable light source module (25) is used for spare fiber monitoring. The OSM optical switch module (26) is used for the test requirements of automatic switching selection of multiple tested optical fibers. The OTDR module (21) selects a suitable dynamic range according to different measurement distances. S3. Utilize high-precision OTDR measurement technology, combined with geographic information system (GIS) and satellite positioning (GPS) technology, and use the original line data for data comparison and analysis to accurately locate the fault. By comparing and analyzing the new and old OTDR curve data, it is possible to promptly discover potential faults that have not yet occurred but will cause communication interruption and provide accurate warnings, so that timely repairs can be performed before the fault occurs.
