Abstract :
The optimum profile parameter on germanium phosphosilicate graded-index optical fibres at 1.27 ¿m wavelength is examined experimentally and is found to be 1.88 ± 0.01. Graded-index optical fibres that simultaneously possess high transmission bandwidth (in excess of 1 GHz km) and attenuation below 1 dB/km are obtained.
