To increase the transmission capacity of multimode fiber (MMF) drastically, Mode Group Division Multiplexing (MGDM), an optical MIMO technique, can be applied. With MGDM, different mode groups, propagating in MMF are used to carry different information. In this paper, Orthogonal Frequency Division Multiplexing (OFDM), a multi-carrier modulation scheme which not only can make efficient use of the available spectrum but is more resistant to frequency selective fading is proposed in an MGDM system. Simulation results of a 2 x 2 OFDM MGDM system operating at high bitrates will be presented and discussed and an improved performance is shown.
