Paper Abstract

Germanate glass (Ge02-Sb203) optical fiber has been drawn from a preform glass rod prepared by the vapor-phase axial deposition (VAD) method. Transmission loss as low as 13 dB/km at the 1.1 Am wavelength has been obtained for a silicone resinclad fiber, and 5 dB/km at 2 Am and 23 dB/km at 2.4 Am have been obtained for a fiber with germanate glass cladding. If a germanate glass fiber of ideal design with a water content as low as 1 ppb (as has already been achieved for high-silica fiber prepared by the VAD method) is prepared, a loss of less than 0.1 dB/km is anticipated around the 2.2 to 2.4 Am wavelength.
