Abstract
An object of this invention is to realize 20 Gbit/s or more high speed WDM transmission over 6000 km. A dispersion compensating optical transmission line consists of a first optical fiber composed of an optical fiber whose chromatic dispersion becomes zero at a 1.3 .mu.m band, a second optical fiber composed of an optical fiber whose chromatic dispersion becomes zero at a 1.3 .mu.m band, and a dispersion/dispersion slope compensator which is substantially a linear optical device disposed between the first and second optical fibers to compensate for chromatic dispersion and dispersion slope of the first and second optical fibers.
