In order to improve the data transmission efficiency of the distribution network,the data transmission scheme based on optical fiber communication is adopted in this paper,which improves the data transmission speed and system reliability.The data transmission method of the distribution network can be used in optical fiber communication,and the Omate series optical transceiver is added(the equipment adopts industrial-grade design,which can adapt to harsh environmental conditions,and the operating temperature range covers-40℃~+85℃).This series of optical transceivers has low power consumption characteristics,and can automatically switch to the backup line in the event of optical fiber line failure to ensure the continuity of communication.In terms of real-time data collection,the system can reach a speed of 1000 times/second,with strong data processing capability and a delay of less than 10ms.After 720 hours of continuous system stability testing,it is proved that the system has the ability to operate without obstacles.The modular design allows the system to support a large number of module expansions(more than 5 kinds),and the communication error bit rate is lower than 10^-9,which ensures the high reliability of communication.The system can work normally under extreme temperatures,and the power consumption is lower than the average level of congeneric products.The fiber optic fault switching time is less than 50ms,which meets the high reliability requirements of the distribution network for data transmission.
