FIBRE POUR LA COMPENSATION DE DISPERSION CHROMATIQUE EN BANDE D'UNE FIBRE MONOMODE

摘要

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/(nm2.km), and an effective area greater than or equal to 14 mum2 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.
