Abstract:
An optical fiber transmission line made up of a succession of segments connected together in series, each of the segments extending from an inlet to an outlet of said segment, and including a succession of elements connected together in series, which succession of elements includes the following, starting from said inlet:a single-mode optical fiber extending substantially to said outlet of said segment for guiding at least one carrier wave, the fiber having an effective mode area and chromatic dispersion for said wave, and also having a spectrum gradient of said dispersion, said fiber constituting a line fiber; and a dispersion compensator disposed at said outlet of said segment and compensating at least a major portion of said chromatic dispersion of the line fiber and/or of said gradient of said dispersion; wherein said effective mode area of the line fiber is greater than 150 &mgr;m2 for one of said carrier waves having a wavelength of 1,550 nm.
