Abstract: PROBLEM TO BE SOLVED: To provide a dispersion compensating optical fiber and a transmission system which compensate dispersion in the case of using a transmission fiber having zero dispersion in the wavelength of about 1310 nm in the band of 1550 nm. SOLUTION: The dispersion compensating optical fiber is provided with negative dispersion and zero or a negative dispersion gradient within the wavelength range of 1520 nm to 1565 nm. It its embodiment, the fiber is composed of a central core region 100 and a clad 101, and dispersion gradient within range of the wavelength including in the middle a core mode region 105 having a lower refractive index than that of the clad, a core ring region 102 having a refractive index between that of the central core region and that of the clad and a second core mode region 103 having a lower refractive index than that of the clad exists between zero and -1.2 ps/nm -km. The dispersion compensating fiber can be combined to a fiber amplifier in order to form a compensator for reducing an additional loss by it. In an embodiment, the dispersion compensating fiber is a distribution fiber amplifier.

Abstract: PROBLEM TO BE SOLVED: To provide dispersion compensating optical fibers which compensate dispersion in the case where a transmission fiber having zero dispersion in about 1,310 nm are used in a 1,550 nm band, and to provide a transmission system. SOLUTION: The dispersion compensating optical fibers can provide larger dispersion more negative than -20 ps/nm-km and attenuation less than 1 dB/km at wavelengths in the 1,520 to 1,565 nm region. Certain of the dispersion compensating fibers also exhibit a dispersion versus wavelength relationship having a negative slope in the above wavelength region, in order to compensate the dispersion versus wavelength slope of the transmission fiber. An example of the structure includes a core moat region 55 consisting of a central core region 50 and a cladding 51 and having a refractive index lower than that of an intermediate cladding, and a core ring region 52 having a refractive index between those of the central core region and the cladding. The dispersion compensating fiber can be combined with a fiber amplifier to form a compensator for reducing additional loss due to the dispersion compensating fiber. In one embodiment, the dispersion compensating fiber is a distributed fiber amplifier.

Abstract: PROBLEM TO BE SOLVED: To manufacture a dispersion compensation fiber with high negative dispersion value and a large effective area. SOLUTION: A preform to be stretched having a core glass region and a surrounding clad layer is formed and stretched by >=100 g stretching into a waveguide fiber having 125 to 170 μm outer diameter. The waveguide fiber is coated with at least one layer of a polymer material. The coated waveguide fiber is heat treated to substantially remove the residual stress in the coating. The core glass region consists of at least three segments and the surrounding clad layer surrounds the core glass region and has the refractive index nc lower than that of at least a part of the core glass region. The radii r1 and ri and relative refractive index percentages Δ1% and Δi% are selected so as to show negative total dispersion

Abstract: A dispersion compensating single mode optical waveguide fiber designed to change the wavelength window of operation of a link from 1301 nm to 1550 nm. The dispersion compensating waveguide fiber is characterized by a core glass region refractive index profile comprised of at least three segments (2, 4, 6, 8). The segment (2) on the waveguide center has a positive relative refractive index. At least one segment (4, 8), spaced apart from the waveguide centerline has a negative relative refractive index.

Abstract: Disclosed is a method of making a hydrogen resistant optical waveguide fiber. The soot preform is heated and immersed in a metal halide gas. A reduced metal species is thus incorporated into the glass soot prior to sintering or consolidation of the soot preform. A hydrogen absorption band around 1530 nm is substantially eliminated from waveguides made from a precursor gas treated preform.
