Wavelength Division Multiplexing Transmission System with Narrow-band Filter

The invention concerns to field of telecommunications, particularly to optically multiplexed transmission systems. Its aim is to enlarge spectral efficiency of wavelength division in multiplexing transmission systems. This aim is achieved by applying in the optical receiver quasi-rectangular optical filter of 18.75 GHz providing transmission bandwidth at 3 dB level. Thus frequency interval between adjacent channels is reduced and data transmission speed for each channel is kept fixed. Invention scheme is realized with frequency interval not less than 37.5 GHz between adjacent channels by keeping fixed data transmission speed 10 Gbit/s for each channel. In such way spectral efficiency of wavelength division multiplexing system is enlarged.
