Resource management system based on optical cable on-line monitoring

The invention discloses an event analysis method based on an OTDR curve optical cable test, and the method comprises the steps of adjusting test parameters at a user terminal, and obtaining a monitoring station test curve through a central control unit; adjusting an analysis parameter threshold value of an event analysis unit of the central control unit at a user terminal; and using the central control unit for analyzing the test curve by the event analysis unit after the parameter threshold is adjusted. The beneficial effects of the invention are as follows the whole optical cable line can bemonitored remotely and online; the change and the change trend of the optical fiber characteristics are monitored in real time; the optical cable resource information of each monitoring station is timely mastered, faults are timely found and alarmed, the optical cable faults are effectively reduced and prevented, and through the optical cable test analysis based on an OTDR curve, the analysis ofthe parameter data of the
