The suggested numerical method is suitable to any multi- layer index profile (including W-fiber and conventional fiber) and sufficiently accurate if fiber materials for successive layers have small index differences. The general characteristics of multi-layer fiber such as cutoff wavelength and dispersion are obtained employing this model.
