Abstract :
The attenuation performance of SiO2/GeO2/P2O5 core graded index multimode fibres at 1.6 ¿m has been studied in relation to changing P2O5 concentrations. Loss is related to both P2O5 doping and OH contamination levels, and reduction of both has led to a minimum fibre attenuation of 0.23 dB/km at 1.62 ¿m.
