Abstract: <P>PROBLEM TO BE SOLVED: To provide a wavelength division multiplex transmission system for separating wavelength division multiplex signals obtained by applying wavelength division multiplexing to optical signals with different bit rates in accordance with the bit rates and respectively individually processing the wavelength division multiplex signals.  <P>SOLUTION: A non-equality bandwidth interleaver 10 divides wavelength division signals, wherein low-speed bit rate signals are arranged in an odd channel group and high-speed bit rate signals are arranged in an even channel group into a low-seed signal group and a high-speed signal group. The low-speed signal group is processed (for example, frequency separation, dispersion compensation, etc.,) by an optical device suitable for a low-speed signal, and the high-speed signal group is processed by an optical device suitable for a high-speed signal. Since this can apply an optical device that is relatively expensive and has a high function only to the high-speed signal side, an increase in device cost can be suppressed, and in addition, a device with spec suitable for each signal can be used.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
