Prechirp technique for dispersion compensation for a high-speed long-span transmission

Dispersion compensation by the prechirp technique is theoretically investigated, and experimental results are discussed. An improvement of more than two times was observed for dispersion-limited transmission lengths in 5-Gb/s, 150-km and 10-Gb/s, 50-km transmission with a semiconductor electroabsorption external modulator and a normal fiber. An allowable transmission fiber dispersion of 10000 ps/nm and 2.5 Gb/s is estimated by computer simulation with this prechirp technique.<
