Paper Abstract

Germano-silicate optical fibres have been fabricated by MCVD with a refractive index difference between the core and the cladding glass of up to 0.05. It is demonstrated that by depositing within Vycor tubes during preform fabrication, fibre may be subsequently drawn at lower temperatures than are possible with conventional silica preforms and this reduces the germania-induced excess loss. The performance of such fibres as Raman fibre amplifiers is discussed with particular reference to their bandwidth for applications in 1.5 - 1.6 AM telecommunications systems.
