10Gbit/s NRZ error-free fibre transmission over distances exceeding 40
0 000 km is demonstrated using an optically amplified regenerator with
a 160km span. Direct modulation of a DFB laser raises the stimulated
Brillouin scattering power threshold while maintaining system simplici
ty and robustness.
