Abstract :
A 1.52 ¿m 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.
