Control and Management Technology of GPON

According to the protocol of ITU - T G984, this paper describes the software and hardware techniques to realize gigabit- capable passive optical networks (GPON) system. Control and management technologies are pointed out as the key issues to guarantee the network maintenance, operation management and stable function. The structure of GPON and function modules is presented. The software of management and control in GPON system and the technology of operation management maintenance are mainly discussed, which is the important reference for designing the optical network unit (ONU) and communicate with optical line terminal(OLT).
