We have demonstrated an optical preamplifier with a record sensitivity of -38.8 dBm (102 photons/bit) at 10Gbit/s. When employed in a practical link without an input isolator the sensitivity is only slightly degraded to -37.6dBm (135 photons/bit) by input coupling losses and feedback due to Rayleigh backscattering in the transmission fibre.
