25 GHz spaced DWDM 160/spl times/10.66 Gbit/s (1.6 Tbit/s) unrepeatered transmission over 380 km

Unrepeatered transmission of 160 25 GHz spaced channels at 10 Gbit/s over 380 km is demonstrated. The combination of recent advanced technologies, such as DWDM multiplexing/demultiplexing, large pump power, remote amplification, in-line filtering and FEC, allow this record transmission to be achieved.
