Figure 7

Experimentally measured performance of a 1 Tb/s DP-256QAM super-channel system.

(a) Achievable information rate (as defined by MI and GMI) and the achieved information rate (obtained after the concatenated FEC scheme) as a function of channel number. The received SNR of each optical sub-carrier is also shown. (b) BERpre and BERpost, before and after the SD-FEC stage respectively.
