Patent ID: 8391716

Claim:
A signal transmission method for a peer-to-peer optical network system comprising an optical line terminal, an optical distribution node and a plurality of optical network units, the optical network units connected to the optical distribution node in a tree distribution having an ordered relation, the method comprising the following steps of: (1) enabling the optical line terminal to transmit, in a single wavelength, optic signals comprising a plurality of downstream signals corresponding to the optical network units via the optical distribution node to a first ordered optical network unit of the optical network units; (2) enabling the first ordered optical network unit to capture own dedicated downstream signals of the first ordered optical network from the downstream signals of the optic signals, to combine the remaining downstream signals with own dedicated upstream signals of the first ordered optical network to generate combined optical signals, and to transmit the combined optical signals to the optical distribution node; and (3) enabling the optical distribution node to transmit the combined optical signals received from the first ordered optical network unit to a next ordered optical network unit of the optical network units, and iterating step (2), to allow each of the optical network units to acquire own dedicated downstream signals thereof and to combine own dedicated upstream signals of each of the optical network units with the remaining downstream signals in the combined optic signals of a previous ordered optical network unit, and to allow a last ordered optical network unit to transmit the combined optic signals that comprise all of the upstream signals of the optical network units via the optical distribution node to the optical line terminal.
