Popis: |
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 > + 15dBm and the amplifiers exhibited repeater gains of ˜30dB. |
