The utility model relates to a cable current carrying capacity monitoring system based on the distributed optical fiber temperature measuring method, which comprises a laser driving device matched with a temperature sensing device in a cable. The temperature sensing device is matched with a corresponding optical fiber branching device, an output end of each optical fiber branching device is connected with one end of the cable, the other end of the cable is connected with a distribution cabinet which is matched with a demodulating device, and an output end of the demodulating device is connected with a cable IEC (international electrotechnical commission) computing server which outputs to a terminal client. By adopting the distributed optical fiber temperature measuring technique, important operational parameters of the cable can be obtained, simulation accuracy can be improved greatly through comprehensive analysis of current carrying capacity, and decision basis for guaranteeing safety operation of urban cab
