Abstract

The invention provides an optic fiber monitoring system and monitoring method switching three operation modes freely, relates to the field of power system optic fiber communication and solves the problems that according to an existing optic fiber monitoring device, labor force is wasted, data loss since switching cannot be performed timely and switching cannot be implemented freely. A control processor is connected to an optic power monitoring module, an OTDR testing module, a data acquisition module, an alarming module, a timing controller, a first optic switch and a second optic switch; the control process is assessed with Ethernet through a network interface RJ45 and is connected to an application server and a data server; the data acquisition module is connected to the OTDR testing module and the optic power monitoring module; the timing controller is connected to the OTDR testing module; the optic power monitoring module is connected to the second optic switch; the OTDR testing module is connected to two multiplexers; the alarming module is connected to the data acquisition module. The system is capable of switching three operation modes of operation fibers, bright auxiliary fibers and dull auxiliary fibers freely.
