Abstract:
1. A subscriber premises side optical network unit, comprising: an electrical/optical converting means connected to a center side optical transmission path to carry out photoelectric conversion and reverse photoelectric conversion; an optical network unit functioning section connected to electrical signal input/output ends of the electrical/optical converting means; a serial/parallel converting means connected to parallel signal ends of the optical network unit functioning section to carry out serial/parallel conversion and reverse serial/parallel conversion; and a multi-source agreement interface module connected to serial signal ends of the serial/parallel converting means; wherein the optical network unit functioning section has a signal output control means that halts a down signal from being outputted from the multi-source agreement interface module to external nodes until when it determines that a communication condition with the center is established based on whether a passive optical network (PON) link with the center is established or authentication is established.
