ABSTRACT:
There is provided a dispersion compensating fiber comprising a center core in which a first dopant is doped substantially uniformly, an outer core provided at the outer periphery of the center core, in which the first dopant is doped so as to decrease gradually toward the outer periphery, and a clad provided at the outer periphery of the outer core, in which a second dopant is doped. The second dopant of the outer core is doped so that the viscosity on at least the outer periphery side of the outer core is substantially equal to the viscosity of the clad.
