PROBLEM TO BE SOLVED: To provide an optical multiplexing/demultiplexing transmission device, a control method and an optical multiplexing/demultiplexing transmission control system with cost reduction.SOLUTION: An optical multiplexing/demultiplexing transmission device 0001 includes: wavelength band multiplexing means 0011 for multiplexing two optical signals having mutually different first and second wavelengths respectively transmitted from a first route and a second route; optical add/drop means 0012 for optically adding/dropping an optical signal having a predetermined wavelength among the optical signals multiplexed by the wavelength band multiplexing means 0011, and for passing an optical signal other than the predetermined wavelength; and wavelength band separation means 0013 for wavelength separating the optical signal output from the optical add/drop means 0012 to transmit the separated first and second optical signals to one of the first and second routes. |
