摘要： The invention relates to a method of fabricating an optical fiber with improved control of transmission characteristics. It proposes determining variations in the characteristics of the preform departing from the design characteristics and modifying the diameter of the fiber during drawing as a function of the measured variations. By varying the diameter of the fiber, variations in the preform departing from its design values can be compensated, in other words irregularities of the preform can be smoothed out. This variation limits the effect of preform variations on the propagation characteristics of the fiber.

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. The low chromatic dispersion slope simplifies the management of chromatic dispersion in the transmission system.

摘要： The invention provides a fiber with continuously changing chromatic dispersion; it limits the quantity of dispersion-compensating fiber needed in a transmission system to compensate the cumulative chromatic dispersion in the line fiber. The fiber has a higher chromatic dispersion at a first end than at the other end, referred to as the second end. The chromatic dispersion varies along the fiber, decreasing over at least a portion of the fiber. At the first end the chromatic dispersion can be of the order of the dispersion of a conventional line fiber, i.e. close to 8 ps/(nm.km). At the second end the chromatic dispersion can have a value of the order of 4 ps/(nm.km). The fiber is used as the line fiber in a transmission system at the beginning of a section between two repeaters. The chromatic dispersion in the vicinity of the first end limits non-linear effects at the beginning of the section; the decrease of the chromatic dispersion in the fiber ensures that at its second end the fiber can be connected to a fiber having lower chromatic dispersion. The fiber can be produced with an index profile in the shape of a rectangle and a ring by varying only the indices, and not the radii.
