Abstract
A chromatic dispersion-compensating fiber adapted to compensate the chromatic dispersion of a step index monomode fiber in band S presents chromatic dispersion of less than −40 ps/(nm.km) around 1475 nm, chromatic dispersion slope of less than −0.16 ps/(nm .km), and an effective area greater than or equal to 14 &mgr;m around said wavelength value. The fiber is monomode at 1475 nm. The fiber can present a rectangle profile with a buried trench and a ring. It serves to compensate chromatic dispersion and chromatic dispersion slope for transmission systems in band S using a step index monomode fiber as the line fiber.
