  • Patent number: 8837889
    Abstract: An optical transmission fiber comprises a central core having an index difference ?n1 with an outer optical cladding; a first inner cladding having an index difference ?n2 with the outer cladding; and a second buried inner cladding having an index difference ?n3 with the outer cladding of less than ?3·10?3. The second buried inner cladding moreover contains Germanium in a weight concentration of between 0.5% and 7%. The fiber shows reduced bending and microbending losses while exhibiting the optical performances of a standard single-mode fiber (SSMF).

  • Patent number: 8265439
    Abstract: An optical fiber preform comprises a primary preform that includes at least one inner cladding and a central core deposited inside a fluorine doped silica tube. The fluorine doped silica tube has a cross section area that is no more than about 15 percent smaller than the cross section area of the primary preform. The optical fiber preform has a large capacity, may be manufactured at reduced cost, and may be drawn to produce an optical fiber having reduced transmission losses.

  • Patent number: 8265440
    Abstract: A method for manufacturing an optical fiber preform includes the steps of depositing an inner cladding and a central core inside a fluorine doped silica tube and thereafter collapsing the silica tube to form a primary preform. The fluorine doped silica tube has a cross section area that is no more than about 15 percent smaller than the cross section area of the resulting primary preform. The present method facilitates reduced-cost manufacturing of a high-capacity optical fiber preform, which may be drawn to produce an optical fiber having reduced transmission losses.

  • Patent number: 7702204
    Abstract: A method for manufacturing a final optical fiber preform via overcladding of a primary preform having a cross section area is disclosed. The method includes at least one manufacturing step of the primary preform by deposit of an inner cladding and of a central core inside a tube of fluorine-doped silica, the tube being chosen such that it has a cross section area that is maximally about 15% less than the cross section area of the primary preform. With the method of the invention it is possible to manufacture a preform of large capacity at reduced cost which allows the drawing of an optical fiber having reduced transmission losses.

  • Patent number: 7171092
    Abstract: The invention relates to the field of optical fibers for wavelength division multiplex transmission networks. It provides an optical fiber with chromatic dispersion compensation in the S band from 1 460 nm to 1 530 nm having a negative chromatic dispersion at the wavelength of 1 495 nm and at least three core slices, preferably at least four core slices. The single core slice or the first core slice is very deeply buried and preferably has as at the wavelength of 1 495 nm a chromatic dispersion to dispersion slope ratio whose absolute value is from 68 nm to 158 nm.
