Abstract :
In this paper, based on the prototype of a commercial OM2 multimode fiber product, tap delay lines filter model and mode spatial coupling theory, we establish a complete analytical model for coherent optical multiple-input-multiple-output (MIMO) systems over multimode fiber (MMF) with ring launching and receiving. With this model, we transmitted 10Gb/s QPSK signal with frequency pre-distortion over 2500m MMF and achieved error vector magnitude (EVM) less than 0.07 when OSNR is 24dB.
