Abstract

See full text

A first transmission apparatus includes a first transmitter and a first receiver. The first transmission apparatus transmits a first optical signal to a second transmission apparatus, which is generated by modulating first light output by a first light source. The first receiver coherently receives a second optical signal transmitted by a second transmission apparatus using the first light output by the first light source. The second transmission apparatus includes a second transmitter, a second receiver, and a controller. The second transmitter transmits the second optical signal to the first transmission apparatus, which is generated by modulating second light output by a second light source. The second receiver coherently receives the first optical signal transmitted by the first transmission apparatus using the second light output by the second light source. The controller controls a wavelength of the second light to be output by the second light source.
