Abstract
A relay system includes a first and a second communication device at least one of which includes an estimating unit that acquires, based on a dispersion compensation amount acquired by an optical transceiver, an estimated value of a transmission delay period, the transmission delay period being a period during which an optical signal is transmitted through an optical fiber; a specifying unit configured to specify, based on the estimated value of the transmission delay period acquired by the estimating unit, a transmission-related time which is related to transmission of a control code by the first communication device or the second communication device, or a reception-related time which is related to reception of the control code by the second communication device or the first communication device; and a determining unit configured to determine, based on the transmission-related time and the reception-related time, the transmission delay period in downlink or uplink channel.
