Abstract :
Two very narrow absorption bands positioned at 765 nm and at 1273 nm have been found in pure silica and fluorinedoped silica optical fibres. Their origin is probably connected with the preform production technique. Annealing of the preform and different fibre drawing conditions did not influence the absorption bands.
