40-Gbits transmission in dispersion-management links with step-index fiber and linear compensation.
The dynamic behavior of single-channel transmission in standard fibers with strong dispersion management and linear compensating devices was theoretically and numerically analyzed. We compared a single pulse and a pseudorandom sequence to highlight the relevant roles played by nonlinearity-induced spectrum distortion and pulse interaction. As a result, 40/Gbit/s transmission on an 1800-km dispersion-management link with 100-km spans of standard fiber was obtained.
