Optical communication modules for intelligent electric energy meters play an important role in the construction of smart grids.On the basis of the comparisons between and analysis of EPON

PLC

WiMAX technologies

EPON is selected as the communication access network technology for intelligent electric energy meters and the communication flow is designed.On the basis of QCA8829 embedded chips and the fiber-optic interface technology accessible to the EPON systems on the Redhat Linux 2.6.x development platform

the communication system from the master station to the slave station of intelligent energy meters is realized.Test results show that the proposed modules accomplish complete collection and full coverage of information at power distribution side of the smart grids and enable remote cost control and load control to the home.
