  • Patent number: 10193630
    Abstract: A selection and distribution circuit (13) is provided between N optical transceivers (11) and one PON control circuit (12). The selection and distribution circuit (13) selects the optical transceiver (11) corresponding to an upstream frame that time-divisionally arrives, thereby transferring the upstream frame opto-electrically converted by the transceiver (11) to the PON control circuit (12) and distributing a downstream frame from the PON control circuit (12) to each optical transceiver (11). A power supply control circuit (23) stops power supply to at least one of one of optical transceivers (11) that are not used to transfer the frame of the optical transceivers (11) and a circuit that is not used to transfer the frame in the selection and distribution circuit (13). This can reduce the system cost per ONU in the optical transmission system.
