ABSTRACT:
A dispersion compensating optical fiber is connected to an optical fiber having chromatic dispersion at a transmission wavelength to cancel the chromatic dispersion out, thereby making the chromatic dispersion of an entire transmission system at the transmission wavelength substantially zero or making the chromatic dispersion close to zero. The dispersion compensating optical fiber comprises a core consisting of a quartz-based glass and a cladding formed on the surface of the core and consisting of a quartz-based glass, and a coating layer formed on the surface of the cladding and consisting of a resin, and the dispersion compensating optical fiber has an outer diameter of less than 250 .mu.m. The coating layer has a thickness of 20 .mu.m or more and a two-layer structure consisting of at least two layers including an inner layer and an outer layer having a Young's modulus higher than that of the inner layer.
