Abstract

La présente invention concerne une fibre optique à dispersion négative compensant en un laps de temps réduit la dispersion chromatique d'une fibre optique à dispersion positive dans une bande signal de longueur d'onde, et une ligne de transmission optique dotée de ladite fibre. La fibre optique à dispersion négative possède les caractéristiques suivantes à une longueur d'onde de 1550 nm : dispersion chromatique D de -150 ps/nm/km maximum; courbe de dispersion telle que le rapport (S/D) par rapport à la dispersion chromatique D est d'au moins 2.0 X 10?-3¿/nm et de 4.7 X 10?-3¿/nm maximum; et la surface effective d'au moins 12 µm?2¿, mais pas plus de 25 µm?2¿. Pour satisfaire ces exigences, la fibre optique à dispersion négative présente, dans l'ordre indiqué en partant du centre vers la périphérie, une région centrale dont l'indice de réfraction maximum est de n¿1?, une première gaine à indice de réfraction n¿2? (<n¿1?), une deuxième gaine à indice de réfraction de n¿3? (<n¿2?), et une troisième gaine à indicede réfraction de n¿4? (<n¿3?).
