A node device and a power saving method in an optical communication network system that can achieve both of a reduction in startup period and a reduction in power consumption. A node device (110) includes: a plurality of optical transceivers (111) on which a plurality of standby modes can be selectively set, the standby modes including a first standby mode in which the startup period is shorter than an allowable interruption period in the optical communication system and a first amount of power is consumed during standby, and a second standby mode in which the startup period is longer than the allowable interruption period and a second amount of power that is smaller than the first amount of power is consumed during standby; and a power consumption control section (112) which, based on usage states of the plurality of optical transceivers and a predetermined number of optical transceivers that should stand by in the first standby mode, dynamically allocates the plurality of standby modes to the plurality of optical transceivers so that a total amount of power consumption will be smaller.
