Effect of deposition rate on spectral loss of GeO2-P2O5-SiO2 graded index fibres

Low loss, low OH content 0.23 n.a. graded index germanium phosphosilicate fibres have been fabricated using the m.c.v.d. process at rates up to 0.34 g/min with deposited layer thicknesses up to 16 ¿m. The deposition rate did not affect achievement of low loss in the spectral range 0.7 ¿m¿1.7 ¿m.
