3500-km Mode-Multiplexed Transmission Through a Three-Mode Graded-Index Few-Mode Fiber Link

We transmit 33 WDM channels over 3500-km three-mode fiber at record post-FEC spectral-efficiency-distance product of 31500 bit/s/Hz · km. This was facilitated by building a DGD compensated fiber span with low MDL and coherent 6×6 MIMO processing.
