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 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 o f 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 1380nm. A low water content plug (46, 54) used in the manufacture of such a cylindrica l glass body, an optical waveguide fiber having a low water peak, and an optic al fiber communication system incorporating such an optical waveguide fiber is also disclosed.

Abstract: Single mode optical fiber waveguides with reduced bending losses for wavelength range of 1300 nm to 1700 nm are disclosed. The extended ranges are achieved by altering the optical characteristics of the fiber, namely, the MAC 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 refractive index profile as a function of the fiber radius. Figure 6 illustrates a ribbon 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).
