Research on the power information collector of optical fiber based on EPON technology

摘要

EPON(Ethernet Passive Optical Network) technology is a new kind of fiber optical broadband access network technology. The EPON system mainly includes OLT, ONU and ODN. It inherited the low cost of Ethernet and the high bandwidth of light network, so it has Broad prospects of application in the Residential electricity information collection field. Based on above, this paper combines the characteristics of EPON technology and the requirement of information collection system in the Residential electricity, developed the design and application methods of Optical Fiber collection terminal equipment for the power consumption data acquisition system based on EPON technology, which is an important application part of EPON system. This paper mainly studies the hardware and software design of Optical Fiber collector, and its application in the Lain Xiang Community in Beijing.
