Abstract: A cylindrical glass body having a low water content centerline region and method of manufacturing such a cylindrical glass body for use in the manufacture of optical waveguide fiber is disclosed. The centerline region of the cylindrical glass body has a water content sufficiently low such that an optical waveguide fiber made from the cylindrical glass body of the present invention exhibits an optical attenuation of less than about 0.35 dB/km, and preferably less than about 0.31 dB/km at a measured wavelength of 1380 nm. A low water content plug used in the manufacture of such a cylindrical glass body, an optical waveguide fiber having a low water peak, and an optical fiber communication system incorporating such an optical waveguide fiber is also disclosed.

Abstract: Disclosed is a method of making a hydrogen resistant optical waveguide fiber. The soot preform is heated and then immersed in a GeCl4 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.

Abstract: A method and apparatus for producing an optical fiber preform including a metal remover, which operates by adsorption, that removes gaseous transition metal impurities present in a process gas to be provided to a furnace for drying, doping or consolidation. The apparatus and method may reduce attenuation of the resultant optical fiber drawn from the preform.

Abstract: Single mode optical fiber waveguides with reduced bending losses for wavelength range of 1300 nm to 1700 nm are disclosed. The extended ranges ar e achieved by altering the optical characteristics of the fiber, namely, the M AC number, the mode field diameter ("MFD"), and the cut-off wavelength. The single mode fibers disclosed exhibit a lower MFD and higher cut-off wavelength. In addition, optical fiber transmission systems, wave division multiplexing ("WDM") systems, and optical fiber ribbon cables are disclosed that incorporate the single mode optical fiber. Figure 2 shows the refractiv e index profile as a function of the fiber radius. Figure 6 illustrates a ribb on cable (700) with 4 fibers in a matrix material (708). Each fiber consists of a central core (702), a cladding layer (703), a primary (704) and a secondary polymer layer (705) and a colored ink coating layer (706).

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.
