Title: Wavelength division multiplex transmission system using asymmetrical filtering
Inventor: FRIGNAC YANN
IPC: H04B10/2563
Filed: 2001-03-02
Abstract: PROBLEM TO BE SOLVED: To provide a wavelength division multiplex transmission system that can improve a spectrum efficiency while maintaining a frequency selected by frequency grids at a prescribed interval. SOLUTION: A spectral interval of one channel with respect to one-side adjacent channel differs from a spectral interval of the one channel with respect to the other side adjacent channel. A demultiplexed filter in use can more strongly attenuate the spectrum of the channel at a smaller spectral interval with respect to the adjacent channel.
