摘要： The invention provides a step index optical fiber which presents cladding having an index lower than the index of silica and a core with an index higher than the index of silica. The fiber is obtained by drawing a preform made by chemical vapor deposition using a deposition tube of index lower than the index of silica. Inner cladding of index substantially equal to the index of the deposition tube, and then a core of index higher than the index of the inner cladding are deposited in succession therein. The invention makes it possible to obtain a fiber having a large effective area, reduced attenuation, and suitable for being fabricated at low cost by chemical vapor deposition.

The invention also proposes optical fibers verifying the above criteria and suitable for compensating the chromatic dispersion of step index or dispersion shifted line fiber.

摘要： A chromatic dispersion-compensating fiber adapted to compensate the chromatic dispersion of an SMF or an NZ-DSF having positive chromatic dispersion presents chromatic dispersion which is negative and greater than or equal to −150 ps/(nm.km) at a wavelength of 1550 nm, and a theoretical cutoff wavelength longer than 1800 nm. At 1550 nm, the fiber presents a ratio of chromatic dispersion over chromatic dispersion slope lying in the range 30 nm to 500 nm. The fiber can present a rectangle or a trapezium profile together with a buried trench and a ring. It can be used in a line or in a module to compensate the chromatic dispersion and the chromatic dispersion slope in transmission systems in which the line fiber is an SMF or an NZ-DSF having positive chromatic dispersion.
