Novel, periodic-group-delay-complemented dispersion compensation and dispersion-managed solitons enable dense WDM over >20,000 km

摘要

In an all-Raman-amplified, recirculating loop containing 100 km spans, each compensated 80% by DCF and 20% by a PGD (periodic-group-delay) device, we have demonstrated 10G dense WDM over <20,000 km. The novel dispersion compensation causes drastic reduction of collision-induced timing jitter.
