Optical access network system, optical access equipment and optical access method

Abstract

The invention discloses an optical access network system, optical access equipment and an optical access method. The optical access network system, the optical access equipment and the optical access method are used for resolving the problem that an existing optical access network system can not effectively utilize great bandwidth resources of optical signals and can not be compatible with different kinds of access network technology simultaneously. The optical access network system, the optical access equipment and the optical access method utilize the wavelength division multiplexing technology, can largely improve the network bandwidth, increase the number of access users, can connect various standards of optical access networks to the same network, achieve the purpose that the optical access networks are updated and improved in a seamless mode towards higher-rate networks, do not need to replace original equipment, and protect current investment. The optical access network system supports a plurality of operators to simultaneously provide network service in the same network, and the operators do not affect each other.

Description

technical field [0001] The present invention relates to passive optical network technologies in the field of optical access networks, in particular to an optical access network supporting multiple access technologies in an optical access network system based on WDM (Wavelength Division Multiplex) technology Systems, devices and methods. Background technique [0002] With the rapid growth of today's communication services, the optical access network develops rapidly, mainly including point-to-point (P2P) optical access network and passive optical network (PON). The point-to-point optical access network needs to lay an optical fiber between each user and the access office point, and the network construction cost is high and maintenance is difficult. Compared with the point-to-point optical access network, the PON adopts a point-to-multipoint structure, which can greatly reduce the cost of optical fiber. However, in this multi-branch PON network, all optical network units ONU...
