Today, an ultra-high capacity transmission system based on N40 Gb/s channel rate is the most promising approach to achieve multi-terabit/s of capacity over a single fiber. We have demonstrated 5.12 Tbit/s transmission of 128 channels at 40 Gbit/s over 3100 km and 10.24 Tbit/s transmission of 256 channels at 42.6 Gbit/s (using FEC) over 100 km, based on four main technologies: 40 Gbit/s electrical time-division multiplexing (ETDM), vestigial sideband demultiplexing (VSB), advanced amplifier technology including Raman amplification and TeraLightTM fiber. A record spectral efficiency of 1.28 bit/s/Hz is applied to achieve 10.24 Tbit/s transmission within the C- and L-band.
