1. An optical transmitter, comprising:
- a plurality of optical modulators, each and a driver by which a modulation format is variable; and
a wavelength selection unit configured to selectively outputs modulation optical signals generated by the optical modulators to a first output port corresponding to a first optical transmission degree and a second output port corresponding to a second optical transmission degree in a unit of wavelength.
