Abstract: Low-loss glass-fiber waveguides were developed. They had a quartz glass (fused silica) cores and borosilicate cladding. The numerical aperture of these fibers was ~0.17. An investigation of the spectral dependence of the total attenuation in the λ = 0.5–1.1 μ range indicated that in the frequency intervals of greatest interest in optical communication (0.8–0.9 μ and 1.06 μ), the total attenuation was less than 10 dB/km.
