Abstract: PROBLEM TO BE SOLVED: To suppress the thermal aging of an optical waveguide improved in dispersion and the attenuation by hydrogen aging by inserting a first core region into the central opening of a second core region in a furnace and forming a segment core region of a waveguide preform. SOLUTION: The first core region consisting of a glass rod doped with fluorine is inserted through the second core region 12 into the central opening 18. Both of the first core region and the second core region 12 are installed in a consolidation furnace 15 and chlorine is passed in an arrow 16 direction between the central opening 18 of the second core region 12 and the first core region. More preferably a muffle gas contg. helium is passed in an arrow 17 direction. The first and second core region assembly is lowered little by little into the zone of the furnace 15 kept at least at about 1400 deg.C to cause consolidation together with the first and second core regions. Consequently, the first and second core regions are consolidated and the segment core region of the preform blank is formed.

Abstract: PROBLEM TO BE SOLVED: To provide a single mode light waveguide fiber designed to restrict a power penalty due to four optics mixtures and a manufacturing method of that waveguide. SOLUTION: A characteristic change such as radius (diameter 83, 84) or refractive index, for example, of a waveguide fiber core gives all divergence along the length of a waveguide. An algebraic summation of multiples of the length and all divergence is controlled to a pre-selected value toward each waveguide constituting a system link. When the size and the small length part of the change of all divergence is properly selected, a system link with which a signal advances by a short distance in a waveguide part having all divergence close to zero is obtained. However, the change of all divergence gives the system link generating a distributed effect pre-selected for the signals in the wavelength range pre-selected. The distributed effect against the signals can be selected to be substantially zero. A veriety of techniques for manufacture of DM fibers is disclosed.

Abstract: Disclosed is a dispersion compensating and dispersion slope compensating single mode optical waveguide fiber. The refractive index profiles of waveguide fibers in accord with the invention are disclosed and described. These index profiles provide a waveguide fiber having negative total dispersion and negative total dispersion slope so that a standard waveguide fiber is compensated over an extended wavelength range. A telecommunications link using the fiber in accord with the invention is also disclosed and described. A standard fiber to compensating fiber length ratio in the range of 1:1 to 3:1 is shown to give optimum link performance with respect to limiting non-linear dispersion effects.

Abstract: A pulse-reshaping optical fiber having a core with refractive index nc surrounded by a cladding layer, the diameter of the core changing monotonically along the length of the fiber. The core includes a central region having a maximum refractive index n1 and a moat region disposed radially adjacent to the central region. The moat region has a minimum refractive index n2 which is sufficiently low that the index delta DELTA 2 of the moat region with respect to nc is not greater than 0.1 %. The moat region affects the change in dispersion with respect to fiber cladding diameter, as well as providing the pulse-reshaping fiber with low dispersion versus wavelength slope. The pulse-reshaping fiber is particularly useful in association with optical transmission systems where high transmission rates and narrow pulse widths are desired, including components such as high pulse rate wavelentgh-division-multiplexers (WDMs) and optical regenerators.
