Patent number: 6904213Abstract: 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.Type: GrantFiled: May 2, 2002Date of Patent: June 7, 2005Assignee: AlcatelInventors: Ludovic Fleury, Louis-Anne de Montmorillon, Florent Beaumont, Pierre Sillard, Maxime Gorlier, Pascale Nouchi, Jean-Florent Campion, Christine Labatut

Patent number: 6856725Abstract: The field of the invention is that of chromatic dispersion compensation modules and of methods of designing chromatic dispersion compensation modules. The design method includes an optimization step consisting in reducing an original quality criterion at a chosen constant average figure of merit for the compensation optical fiber by increasing the attenuation of the compensation optical fiber. The compensation optical fiber of the module has chromatic dispersion more negative than a first threshold and, for a given figure of merit, attenuation that is sufficiently high for the quality criterion to be less than a second threshold and a quality-to-price ratio criterion to be less than a third threshold.Type: GrantFiled: September 22, 2003Date of Patent: February 15, 2005Assignee: AlcatelInventors: Pierre Sillard, Bruno Dany, Alain Bertaina, Maxime Gorlier

Patent number: 6850680Abstract: The fiber is adapted to compensate chromatic dispersion and chromatic dispersion slope of a positive chromatic dispersion optical fiber in the U band from 1625 nm to 1675 nm. In that band it has negative chromatic dispersion, negative chromatic dispersion slope, and a chromatic dispersion over chromatic dispersion slope ratio from 100 nm to 600 nm. At a wavelength of 1650 nm it has bending losses less than 100 dB/m with the fiber wound around a 10 mm radius former and bending losses less than 5×10?3 dB with 100 turns of the fiber wound around a 30 mm radius former.

Patent number: 6819850Abstract: 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.Type: GrantFiled: August 26, 2002Date of Patent: November 16, 2004Assignee: AlcatelInventors: Pierre Sillard, Florent Beaumont, Ludovic Fleury, Maxime Gorlier, Louis-Anne de Montmorillon, Pascale Nouchi
