Field of the Invention [0001] The present invention relates to a pseudo-spaced multi-channel frequency generator using a Pable-Perot resonator composed of a medium with high color dispersion in a multi-channel optical transmission system using optical frequency (or wavelength) division multiplexing technology. Multi-channel light source means 10 composed of a plurality of light source elements arranged at intervals; First optical coupler means (20) for dividing and outputting the light output of the multi-channel light source means (10); A second optical coupler 30 which receives the divided optical output of the first optical coupler means 20 and multiplexes into one optical output; Reference resonating means (40) configured to receive an output of the second optical coupler (30) and be composed of a medium having high color dispersion to generate an equal interval frequency; An optical frequency stabilization means (50) for adjusting the temperature and the applied current of the multi-channel light source means (10) by receiving the output of the reference resonance means (40) and detecting a change in the optical output according to the optical frequency change; External modulation means (60) for modulating a pseudo-equal interval frequency output from the first optical coupler means (20) by an external signal input; And a third optical coupler 70 which receives the output of the external modulating means 60 and transmits the multiplexed optical signals. The third optical coupler 70 efficiently suppresses crosstalk due to four-wave mixing of the optical fibers, and transmits the zero-dispersion wavelength region of the optical fibers. It is possible to realize a large-capacity multi-channel optical transmission system by fully utilizing the bandwidth, and to easily set, control, and filter the frequencies of the multiple transmission channels, thereby making it compatible with different systems using a Fabry-Perot resonator composed of the same medium. There is an effect that can implement an optical frequency (or wavelength) divided multiple optical transmission system.
