The short range plastics optical fiber communication method comprises the following steps: an information collection step, an information classifying step, an information coding step, an information transmitting step and an information decoding step. The information collection step is used for collecting the fault information and the electric current load information of the power transmission line in real time. The information classifying step is used for judging the collected information and conforming kinds of the information. The information coding step is used for coding the collected fault information or the collected electric current load information combined with information sending content of different kinds of the information and according to a coding standard. The information transmitting step is used for sending the coded information to a power distribution main station at a time interval T. The information decoding step is used for decoding the received coded information according to the coding standard. According to the short range plastics optical fiber communication method, the fault information can be teletransmitted and the electric current load information can be uploaded. Electric current of the electric transmission line can be obtained according to analysis of an analog to digital (A/D) sampling value of the uploaded electric current load information so that an actual operation state of a device in site can be controlled easily.
