A 1.52 μm wavelength 8 Mbit/s system using heterodyne detection is demonstrated over 30 km of installed monomode fibre cable. Sensitivity improvements of 14 dB over direct detection were obtained at the remote receiver with only -27 dBm local oscillator power. It was not necessary to use special polarisation-maintaining fibre to obtain these results.
