Abstract
By limiting the ranges of the numerical values of a plurality of structural parameters of a dispersion compensating optical fiber which is endowed with a segmented W-shaped refractive index profile, and by suitably combining these structural parameters, it is possible to obtain a dispersion compensating optical fiber which can compensate both for chromatic dispersion and also for dispersion slope of a single mode optical fiber for transmission over a wide wavelength band which is selected from the range from 1.53 &mgr;m to 1.63 &mgr;m, and for which the value of Aeff is large, and moreover the absolute value of chromatic dispersion is large. As a result desirable transmission characteristics are obtained by being able to suppress the occurrence of nonlinearity effects, and furthermore, since the length which is required is short, the cost is low, and it is possible to produce a module which is small in size.
