Mode switchable smart optical cable monitoring system and method

The invention discloses a mode switchable smart optical cable monitoring system and method. The system comprises a light source module, a network management server, an RTU unit device and a client computer. According to the system and the method, the problem that an existing optical cable monitoring device cannot realize the fact that three working modes: a standby fiber test, an online test and protection monitoring are taken into consideration by the same RTU device at the same time is solved. The mode switchable smart optical cable monitoring system is provided. When the system is applied,24-hour all-whether real-time automatic monitoring can be carried out on an optical cable state; the system has a relatively high detection probability, a relatively low false alarm probability and the relatively high optical cable breakpoint positioning precision; the system has a rapid optical cable protection switching function; the normal operation of an original transmission system is not influenced; and the system h
