Abstract
Provided is a network system including a subscriber apparatus and a station-side apparatus connected with the subscriber apparatus via an optical line. The subscriber apparatus includes a transceiver for receiving an instruction to change wavelengths for signals to be sent and received, receiving a downstream signal sent from the station-side apparatus and having a wavelength designated by the instruction, and sending an upstream signal having a wavelength designated by the instruction to the station-side apparatus. The subscriber apparatus includes a controller for identifying at least one property of the received downstream signal and determining wavelengths for signals to be sent and received based on the identified at least one property.
