Abstract

Germanate glass optical fiber has been drawn from the preform glass rod synthesized by vapor phase reaction. The attenuation loss as low as 13 dB/km at 1.1 an wavelength has been obtained for the silicone clad fiber, and 134 dB/km at 2.38 μm has been obtained for the fiber with thin germanate glass cladding. If the germanate glass fiber which is designed ideally and which has the reduced water content as low as 1 ppb that has been already achieved for the high silica fiber fabricated by the vaporphase axial deposition (VAD) method is prepared, the attenuation loss less than 0.1 dB/km is supposed to be achievable in a practical sense around 2.2-2.4 µm wavelength.
