Dispersion Shifted Optical Fiber
A dispersion-shifted optical fiber is obtained thathas a refractive index distribution shape comprising acenter core portion of high refractive index, a step coreportion of lower refractive index than the center coreportion, provided about the outer circumference thereof,and clad of lower refractive index than the step coreportion, provided about the outer circumference of thestep core, in which, by suitably setting structuralparameters, both Aeff expansion and dispersion slopereduction are satisfactorily effected, simultaneously,under conditions that the optical fiber is substantiallysingle-mode, and bending loss is held down to 100 dB/m orlower.
