SIGNAL TRANSMISSION DEVICE AND SIGNAL TRANSMISSION METHOD

Japanese Patent JP2010124320

A

To provide a signal transmission device for which broadband transmission in real time is available, with high quality.

This signal transmission device is provided with: a multi-wavelength light source; an optical demultiplexing part for demultiplexing a light beam to be emitted by the multi-wavelength light source into a set wavelength band; a plurality of single carrier signal generating parts each of which converts a serial signal to be input into a parallel signal corresponding to a channel and which outputs a composite signal; a light modulator installed in each wavelength band for modulating the light beam of the wavelength band by the composite signal from the corresponding single carrier signal generating part, and for outputting it as an optical signal; and an optical multiplexing part for multiplexing the optical signal modulated by each light modulator, corresponding to each wavelength band.
