First Claim
1. A multi-flow optical transceiver comprising:
- a plurality of wavelength-tunable light sources;
a plurality of optical modulation units which modulates light with an input signal;
an optical multiplexing/demultiplexing switch which couples light from at least one of the wavelength-tunable light sources to at least one of the optical modulation units with any power;
an optical coupling unit which couples a plurality of lights, modulated by a plurality of the optical modulation units, to at least one waveguide;
at least one multiple carrier generating unit which generates multiple carries, arranged at equal frequency intervals, from light of the wavelength-tunable light source; and
a wavelength separation unit which branches the multiple carriers from the multiple carrier generating unit for each wavelength.
