Abstract: An optical fiber waveguide of the type comprising an outer cladding layer, an axially disposed core of SiO.sub.2 doped with GeO.sub.2 and a first inner cladding layer of SiO.sub.2 doped with an oxide such as P.sub.2 O.sub.5 for lowering the preform processing temperature. A second inner cladding layer of pure SiO.sub.2 is disposed between the first inner cladding layer and the core to prevent P.sub.2 O.sub.5 from diffusing into the core, thereby eliminating absorption losses from the P--O--H band in the 1.1-1.8 .mu.m region.

Abstract: A process for producing an optical transmission fiber is provided which comprises feeding highly pure halides, hydrides or organic compounds of Si and B by way of carrier gas on the outer surface of a fused silica rod or a fused silica pipe, or inner surface of a fused silica pipe, oxidizing them and depositing the products to form a pure fused silica layer or a doped fused silica layer containing B.sub.2 O.sub.3, melting the pipe and the deposited layer followed by a spinning. The SiO.sub.2 layer can alternatively contain fluorine instead of B.sub.2 O.sub.3. A further SiO.sub.2 layer can be deposited thereon to improve the spinning processability and lower the index of refraction of the B.sub.2 O.sub.3 containing layer.
