10 Gbit/s, 100km nonrepeatered fibre transmission experiment using a high-sensitivity semiconductor optical preamplifier

Abstract

10 Gbit/s, 100 km nonrepeatered fibre transmission has been demonstrated using a high-sensitivity receiver with two-stage cascade-connected semiconductor optical amplifiers and a pin PD front end. The sensitivity and its improvement were −23.5 dBm and 12.2 dB respectively, resulting in the allowable span-loss of 24.5 dB.
