摘要： An OLT includes an upper-layer processing unit that receives a transmission request for notifying a data amount transmitted from an ONU and applies predetermined upper-layer processing to data received from the ONU. The OLT includes a band-allocation-information managing unit that instructs, based on the transmission request, when determining that a free period, which is a period in which a band is not allocated to data transmission from the ONU, equal to or larger than a predetermined band threshold is present, the upper-layer processing unit to shift a power saving state. The upper-layer processing unit shifts to the power saving state based on the instruction.
