Performances of an Optical OFDM-DMT System over Multimode Optical Fiber
Résumé
In this paper, we present the orthogonal frequency division multiplexing (OFDM) technique based on discrete multitone modulation (DMT) over multimode fiber (MMF), at length up to 5Km at a bit rate of 20 Gb/s. Through numerical simulations, we investigate the optimal launching conditions of the MMF fiber. The effect of the fiber length on the performances of the system is also studied.
