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 &mgr;m2 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.

摘要： The invention relates to an optical fiber for compensating, in-line, for the chromatic dispersion of an optical fiber having positive chromatic dispersion. For a wavelength of 1550 nm, the optical fiber of the invention advantageously has chromatic dispersion that is negative and greater than −40 ps/(nm.km), a chromatic dispersion gradient that is negative, a chromatic dispersion to chromatic dispersion gradient ratio that is in the range 50 nm to 230 nm, an effective area that is greater than 10 &mgr;m2, and bend losses that are less than or equal to 0.05 dB; and a cutoff wavelength that is greater than or equal to 1.1 &mgr;m. It makes it possible to compensate for the cumulative chromatic dispersion in a line fiber of the NZ-DSF type having positive chromatic dispersion. The invention also relates to an optical fiber transmission system using such a fiber to compensate, in-line, for the cumulative chromatic dispersion in the line fiber.

摘要： The invention relates to a single-mode optical fiber that, for a wavelength of 1550 nm, has an effective area greater than or equal to 60 &mgr;m2, chromatic dispersion lying in the range 3 ps/(nm.km) to 14 ps/(nm.km), a chromatic dispersion gradient in the range 0 ps/(nm2.km) to 0.1 ps/(nm2.km), and a ratio between the effective area and the chromatic dispersion gradient that is greater than or equal to 1000 &mgr;m2.nm2.km/ps, as well as a zero chromatic dispersion wavelength shorter than 1480 nm. The fiber thus has both a large effective area and a shallow chromatic dispersion gradient, and it is thus well suited to wavelength division multiplexed (WDM) transmission. The invention also relates to a WDM optical fiber transmission system that uses such a fiber as the line fiber.

摘要： The invention relates to a dispersion-shifted single-mode optical fiber having an effective area greater than or equal to 60 &mgr;m2. This fiber is characterized by the fact that it has a zero chromatic dispersion wavelength &lgr;0 that is greater than 1585 nm and chromatic dispersion at 1550 nm that is greater in absolute terms than 3 ps/nm.km. The invention is applicable to wavelength division multiplexed transmission systems, and makes it possible to limit non-linear effects, such as four-wave mixing, and to limit the use of dispersion-compensating fiber.

摘要： The invention provides a monomode optical fiber having, at a wavelength of 1550 nm: an effective section area greater than or equal to 60 &mgr;m2; chromatic dispersion close to 8 ps/(nm.km); a chromatic dispersion slope of absolute value less than 0.07 ps/(nm2.km). In the range of wavelengths used in a WDM transmission system, typically 1530 nm to 1620 nm, the fiber has chromatic dispersions greater than 7 ps/(nm.km), thereby making it possible to limit non-linear effects. The invention also provides a WDM optical fiber transmission system using such a fiber as a line fiber. The small slope of its chromatic dispersion is an advantage in such a system.

A "peculiar" one of the cores has a central zone that is not doped by the dopant, the other cores all being completely doped by the dopant, thereby enabling the peculiar core to be used as a local reference point in order to locate the cores of the optical fiber individually.
