The strength of the 242 nm absorption band in MCVD germanosilicate fibre preforms is observed a) to be linearly dependent on Ge concentration and b) to increase by a factor of ~2.5 if O2 is replaced with He during the collapse process. It also reduces when the preform is co-doped with phosphorus, fluorine, aluminium and boron.
