Low-loss fibre prepared under high deposition rate by modified c.v.d. technique

Abstract

Graded-index fibres with a GeO2-P2O5-SiO2 core have been prepared by a modified c.v.d. and drawing process. The deposition rate of the core glass was 0.17 cm3/min (0.37 g/min), and the fibres have an attenuation of 2.6 dB/km at 0.83 μm and a 6 dB bandwidth of 816 MHz km.
