Full C-Band 3060-km DMD-Unmanaged 3-Mode Transmission with 40.2-Tb/s Capacity using Cyclic Mode Permutation

We demonstrate the longest three mode-multiplexed full C-band transmission over 3060 km. The cyclic mode permutation technique enabled DMD-unmanaged transmission across 4.4-THz optical bandwidth over FMF having DMD of > 33.7 ps/km.
