Abstract
In a network that includes one or a plurality of optical line terminals, a plurality of branches, and an optical routing unit, the optical network unit registration method includes a first process in which the optical line terminals transmit a discovery gate to the optical network units, and a second process in which, in response to the discovery gate, an unregistered optical network unit transmits a register request to a separate optical line terminal from the terminal that transmitted the discovery gate. A discovery window is provided in the optical line terminal that receives the register request. This optical line terminal receives the register request in the discovery window.
Claims8
An optical network unit registration method for registering an unregistered optical network unit in a network that includes,
- a plurality of optical line terminals;
- a plurality of branches, each of which includes a branched optical transmission path and an optical network unit connected to a branch destination of the optical transmission path;
- and
- an optical routing unit, which has a plurality of optical communication ports that are divided into a first group connected to the optical line terminals and a second group connected to the optical transmission paths of the branches, and which is configured to output an optical signal input to an optical communication port of one of the groups from an optical communication port of the other group that is determined based on a wavelength of the optical signal,
- the optical network unit registration method comprising:
- a first process in which the optical line terminals transmit a downlink optical signal to the optical network units;
- and
- a second process in which, in response to the downlink optical signal, an unregistered optical network unit transmits an uplink optical signal to a separate optical line terminal from the terminal that transmitted the downlink optical signal.
