Abstract
A sending apparatus includes: a wavelength path multiplexing part; a sending wavelength path selection part; and an optical transmitter having optical sending parts. The wavelength path multiplexing part includes: sending wavelength path demultiplexing ports; and sending wavelength multiplexing ports connected thereto. The sending wavelength path multiplexing ports are connected to optical transmission paths respectively. The sending wavelength path selection part includes a wavelength multiplexing parts which multiplexing a set combination of optical signals among the optical signals inputted to the sending input ports and outputs it to any of the sending output ports. In the wavelength path sending or receiving by the wavelength path multiplexing/demultiplexing optical transmission apparatus, a non-selectable combination between a wavelength and a route can be avoided.
