20 Gbit/s-1850 km and 40 Gbit/s-750 km soliton data transmissions using erbium-doped fiber amplifiers

摘要: Recently, soliton transmission technology has matured considerably through the use of erbium-doped fiber amplifiers (EDFAs).1,2 In order to show that several advantages over conventional IM/DD or coherent systems, it is now important undertake single-pass long-distance high-speed data experiments with pseudo random signals, as already been demonstrated in linear systems NRZ signals.3-5 response this need, such 5 Gbit/s-3000 km, 10 Gbit/s-1200 and 20 Gbit/s-1020 km (under a completely penalty-free condition) transmissions have reported recently.6-8 However, possibility extending distances increasing bit-rates are still under investigation. paper, we report for first time Gbit/s 1850 40 750 experiments.
