Abstract
A transmission system for relaying communication of communication systems includes a relay unit configured to relay uplink communication and downlink communication of a communication system that performs a time division duplex (TDD) mode through signals of different wavelengths, an information acquisition unit configured to acquire time division information indicating timings of the uplink communication and the downlink communication in the communication system that performs the TDD mode, a calculation unit configured to calculate a free period unused in relaying of communication of the communication system that performs the TDD mode on the basis of the time division information for each wavelength, and an instruction unit configured to instruct the relay unit to relay communication of another communication system different from the communication system that performs the TDD mode in the free period for each wavelength calculated by the calculation unit.
