MURRAY HILL, N.J., Mar. 20 -- Scientists at Bell Labs, the research and development arm of Lucent Technologies, have demonstrated the first long-distance triple-terabit data transmission. The researchers sent a record 3.28 Tb/s over 300 km of an experimental Lucent TrueWave optical fiber. Bell Labs scientists used three 100-km fiber spans to transmit 40 Gb over each of 40 wavelengths in the conventional C-band frequency range and 40 Gb over each of 42 channels in the long-wavelength L-band range. The demonstration employed both dense wavelength division multiplexing and distributed Raman...Read full article
