REGISTRATION ACTIVATION METHOD, DEVICE AND SYSTEM FOR ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING PASSIVE OPTICAL NETWORK

摘要

Provided are a registration activation method, device and system for an orthogonal frequency division multiplexing passive optical network. A registration activation method for an orthogonal frequency division multiplexing passive optical network, comprising: sending, by an optical line terminal, a downlink training sequence to an authenticated optical network unit; receiving, by the optical line terminal, a downlink bit bearer table of the optical network unit and an uplink training sequence which are sent by the optical network unit, the downlink bit bearer table of the optical network unit being calculated by the optical network unit according to the downlink training sequence; calculating, by the optical line terminal, an uplink bit bearer table of the optical network unit according to the uplink training sequence; calculating and updating, by the optical line terminal, a system downlink bit bearer table and a system uplink bit bearer table according to the downlink bit bearer table of the optical network unit and the uplink bit bearer table of the optical network unit, and sending the system downlink bit bearer table and the system uplink bit bearer table to the optical network unit, so that the optical network unit updates the system downlink bit bearer table and the system uplink bit bearer table.
