Ultra-low nonlinearity low-loss pure silica core fibre for long-haul WDM transmission

A new design of pure silica core fibre with an effective area >110 /spl mu/m/sup 2/ and attenuation of 0.171 dB/km at 1.55 /spl mu/m has been successfully developed. It exhibits ultra-low nonlinearity and excellent bending loss performance.
