Scalable Dispersion Management for Hybrid 10-Gb/s and 40-Gb/s DWDM Transmissions with High Nonlinear Tolerance

We present a scalable dispersion management scheme that offers essentially distance-independent dispersion accumulation by the use of distributed interleaved periodic-group-delay dispersion- compensation modules for transparent DWDM transmissions. It is also shown by numerical simulations to offer high nonlinear tolerance for both 10-Gb/s and 40-Gb/s traffics, attractive to data-rate-mixed long-haul networks.
