Abstract: In order to comply with the current sustainable and intelligent development trend of the power industry, an efficient, accurate and reliable power information collection system is constructed applying all-fiber networks to intelligent electricity meter reading. In the local backbone communication network, plastic optical fiber is used as a signal transmission medium, while in the remote channel, quartz optical fiber is used for large- scale and long-distance data transmission. The corresponding optical transceiver modules are added to the measurement equipment and communication nodes, which can make the power meter reading system all-optical. The experimental results show that all-optical sultion will improve the successe rate of meter reading to 100% , reduce time consumption to 2. 1 s and power consumption to 50 mW. It will bring more intelligent value-added functions to the power industry, laying a solid technical foundation for the modernization of electricity and various energy industries.
