Abstract
An optical communications network that is composed of one station-side equipment being connected to plural subscriber-side equipments. The station-side equipment refers to downstream data signals and prepares transmission plans, and generates downstream control signals that include the transmission plans, and converts downstream signals, that include the downstream data signals and the downstream control signals to which identifiers indicating the subscriber-side equipments that are addressees are assigned, into downstream optical signals, and sends the downstream optical signals out toward the subscriber-side equipments. The subscriber-side equipment converts downstream optical signals into downstream electric signals, and refers to identifiers and extracts downstream electric signals addressed to itself, and reads the transmission plans, and generates timer control signals including information of receiving start times and receiving stop times, and, on the basis of the timer control signals, opens and closes a path connecting a receiving section and an electricity supply section.
