摘要： At a wavelength of 1 550 nm an optical fiber has a chromatic dispersion from −12 to −4 ps/(nm.km) and a ratio of chromatic dispersion to chromatic dispersion slope from 250 to 370 nm. Its index profile comprises a rectangle or trapezium with a buried trench and a ring. An optical fiber transmission system uses this kind of fiber to compensate cumulative chromatic dispersion in a line fiber that has at a wavelength of around 1 550 nm a chromatic dispersion from 5 to 11 ps/(nm.km) and a ratio of chromatic dispersion to chromatic dispersion slope from 250 to 370 nm.

摘要： An optical fiber in which propagation is monomode propagation when incorporated into a cable has, at a wavelength of 1 550 nm, a chromatic dispersion from 3 ps/(nm.km) to 14 ps/(nm.km) and an absolute value of chromatic dispersion slope less than 0.014 ps/(nm2.km), and, at a wavelength of 1 625 nm, bending losses measured for a 10 mm radius less than 400 dB/m. The proposed criteria allow use of the fiber over a wide band of wavelengths in a wavelength division multiplex transmission system.

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.
