Wideband WDM coherent optical MIMO transmission over 50 ?m-core GI-MMF using selective mode excitation technique
We proposed a MIMO system by using a selective mode excitation technique to reduce DSP complexity. We obtained a small DMD over a wide wavelength range under selective mode excitation conditions. We achieved a C+L band WDM coherent optical 22 MIMO transmission over a 10-km 50?m-core GI-MMF.
