Abstract :
We demonstrate that frequency packing technology breathes new life into existing optical networks by allowing terabit super-channel transport against common opinion that expensive flex-grid infrastructure upgrade is required. 4.2 to 5.69 b/s/Hz spectral efficiency is obtained over ULH reach.
