Use of dispersion managed fibers in parallel WDM systems

The problem of serial electronic bottleneck in optical systems can be solved using parallel transmission. In these systems, there is no need for serial-to-parallel, and parallel-to-serial conversion since all bits in a digital word are transmitted simultaneously. Several parallel systems have been proposed in the literature and some of them are already commercially available. In this paper, the feasibility of a novel parallel WDM system using Dispersion Managed Fibers (DMF) is proposed. 10 GWord/s over 40 km of DMF at an aggregate bit rate-distance product of 160 Gbit/s/spl times/40-km is studied.
