Due to its enormous bandwidth, Multi-Mode Fiber (MMF) seems the only medium able to offer a broadband multiservice system using Mode Group Diversity Multiplexing (MGDM) technique. As an Optical Multiple Input Multiple Output (O-MIMO) method, MGDM exploits efficiently the fiber bandwidth by spatial launching and reception, so that the capacity is increased. However, the propagation of modes in the MMF is subjected to several spreading effects which disturb and degrade the transmission performance of the optical fiber. In addition, the choice of optimal injection and reception conditions are not enough to improve the transmission, but the mechanical effects acting on the channel play an important role in the use of this technique.
