3.2 Tb/s-1500 km WDM transmission experiment using 64 nm hybrid repeater amplifiers

3.2 Tb/s (160/spl times/20 Gb/s) RZ signals were transmitted over 1500 km precisely-flattened dispersion managed line with the use of newly developed 64 nm hybrid amplifiers. This is the first demonstration of multi terabit/s, long distance transmission.
