Abstract :
This letter proposes all unequally spaced channel allocation method that increases the number of channels around the zero-dispersion wavelength region. The validity of this method is confirmed by numerical simulation considering the fluctuation of the zero-dispersion wavelength existing along the installed 1.55-μm dispersion-shifted fibers (DSF´s). A 22×10 Gb/s transmission experiment over 320 km of DSF using the wavelengths ranging from 1532 to 1562 nm is successfully conducted by employing this method.
