Compensating Multimode Fiber Dispersion Using Adaptive Optics

Abstract :
In multimode fiber (MMF), principal modes are free of modal dispersion to first order. Using adaptive optics for controlled excitation of principal modes enables transmission far beyond the traditional bandwidth x length product. This technique scales much better than electrical equalization to multiple WDM channels, high bit rates and long fibers. We have demonstrated 10 Gbit/s NRZ transmission through 11 km of standard 50 mum graded-index MMF.
