The present invention relates to an optical fiber management system. The optical fiber management system according to the present invention comprises: a monitoring module including a tap coupler for separating a part of an optical signal of an operating cable connected to an optical network, and a photodiode for receiving the part of the optical signal separated from the tap coupler, and sensing and outputting the intensity of the optical signal; an optical signal detection module which receives the intensity of the optical signal outputted from the photodiode and transmits the same to OTDR, generates an hacking alarm when the intensity of the optical signal is received at a reduced intensity than that of a normally received optical signal and transmits the same to the OTDR, and generates a switching control signal to switch over to a spare cable, when the operating cable is broken, and transmits the same to a first switch and a second switch connected to the first switch; and a switching module which is positioned by being connected to the second switch to receive the switching control signal through the second switch and to switch the operation from the operating cable to the spare cable. Therefore, the optical fiber management system can be efficiently and flexibly realized by assembling modules according to functions to achieve and the size of the network or increasing the number of modules to be provided. In addition, as a hacking alarm for warning to determine whether an optical fiber cable is hacked or not is generated, hacking of the optical fiber cable, which may occur in an optical communications network, can be prevented and handled. |
