Abstract: 665 and 947 b/s/Hz ultra-highly aggregate spectral-efficient SDM transmission over 9.8km 6-mode 19-core fibre has been successfully demonstrated using 5.7-GHz-spaced 5-Gbaud DP-16QAM/64QAM Nyquist WDM signals with pre-emphasis-based MDL compensation and cladding-pumped 6-mode pre-amplification.
