30 Gb/s 2×2 MDM-DD-OFDM Transmission over 200m Conventional MMF Link without MIMO Compensation

Mode-division-multiplexing of 30 Gb/s 2×2 direct detection OFDM transmission over conventional multimode fiber link is demonstrated. The error-free transmission of unidirectional over 200m OM3 MMF link under FEC-limit is achieved without using MIMO DSP compensation.
