摘要：

The effects of nonlinearity on sub-500 fs pulse transmission over dispersion compensated fiber links using dispersion Compensating fiber technique are investigated numerically and experimentally. The pulse broadening and recompression ratio of the 2.5-km transmission link is over 300, The postcompensated and precompensated links are compared when the; input pulse energy ranges from 15 to 150 pJ, At high powers, self-phase modulation(SPM) degrades the pulse recompression process and provides an upper bound on the transmitted pulse energy. The SPM effect is stronger in the postcompensated link than in the precompensated link. A dramatic spectral narrowing effect was observed in the postcompensated link, Pulse energies up to tens of pJ, consistent with high quality communication, should be possible for a sub-500 fs pulse in such dispersion compensated links.
