Abstract

A field demonstration of two channel 622 Mbit/s DPSK and FSK coherent transmission over 200 km of installed terrestrial fibre and unrepeatered over 264 km of undersea fibre is reported. Diode-pumped erbium-doped fibre amplifiers were used as power boosters and multi-wavelength repeaters. The maximum launch power of the amplifiers was >+15 dBm and the amplifiers exhibited repeater gains of approximately 30 dB.
