Kind Code:
A1
Abstract:
This OLT (110) comprises: first transmission/reception units (122, 123) that perform optical communication with one or more first ONUs; second transmission/reception units (124, 126) that perform optical communication with one or more second ONUs; a power supply unit (142); first transmission/reception control units (127, 128) that control the first transmission/reception units (122, 123); second transmission/reception control units (129, 130) that control the second transmission/reception units (124, 126); and an OLT processing unit (141) that causes the first transmission/reception control units (127, 128) to turn off the power supply to the first transmission/reception units (122, 123) during a first period when the number of the one or more first ONUs is equal to or less than a predetermined number, and causes the second transmission/reception control units (129, 130) to turn off the power supply to the second transmission/reception units (124, 126) during a second period when the number of the one or more second ONUs is equal to or less than a predetermined number.
