Paper Abstract

The main source of bit errors in multi-mode fibers (MMF) transmission systems is the inter-symbol interference (ISI) caused by the differential mode dispersion (DMD) generated multi-path effects. The DMD creates inter-symbol interference and limits the transmission distance-bandwidth product of a MMF to 3OO MHz-km. Hence, at 10 Gb/s data rate, the transmission distance is only -3O meters, which is not very useful for networking. In this work, we propose to utilize the adaptive equalization technique to combat the DMD and increase the transmission distance to almost the desired length. With this technique, we not only obtain MMF-based 10 Gb/s gigabit Ethernets (GE) but also upgrade all the already installed MMFs (OC-3 backbones) to higher-speed pipes. We present simulation results that show the success of our proposed adaptive equalization approach in canceling the DMD generated multi-path effect in MMF transmissions.
