We present a multiple-input multiple-output (MIMO) optical link based on coherent optics and its ability to exploit the inherent information capacity of multimode fiber.  ...  The impact of phase noise is studied with numerical simulation.  ...  In addition, a 30-dB SNR without phase noise was assumed at each receiver to set the noise power for the additive white Gaussian noise (AWGN) source.  ...
