Collision-Induced Impairments in Dispersion Managed Fiber Systems

Recent advances in fiber characteristics of dispersion-managed fiber is reviewed. We have studied the transmission of single channel RZ systems as well as collision-induced impairments in WDM systems in dispersion-managed fibers. With short period dispersion managed fiber, single channel 100 Gb/s is achievable without transmission control. By emplyoing strong dispersion maps, the collision-induced impairments such as four wave mixing and timing jitter due to cross-phase modulation can be suppressed.
