Smart Grid

With the rapid development of intelligent communication and modernization of distribution network, the safe and stable operation of power distribution network has to face the severe challenge. Based on the secure and reliable communication system, the distribution automation system can realize the data transmission, so as to ensure the synchronization and reliability of the control center and the terminal acquisition data.

Ethernet passive optical network (EPON GPON) as a point of the structure of single fiber bidirectional optical access technology, with advantages of high reliability, high safety, economy and good expansion ability, and can be used effectively to ensure the distribution network security data transmission process.
