<p>MANUFACTURE OF MONOMODE FIBERS A monomode fiber has a core, cladding layer and jacketing layer. The cladding layer has a refractive index which is a predetermined value lower than that of the core and a predetermined value higher than that of the jacketing layer. The jacket can be formed by a fused silica tube substrate, the cladding layer of phosphorus doped fused silica and the core of doped fused silica, being doped with either phosphorus or germanium,or both.</p> |
