14. Demonstrated 150G 8QAM / 200G 16QAM from L2/L3
modular switch over a fully-filled, flexible-grid OLS
Excellent back-to-back OSNR sensitivity:
• 8QAM at 14.2 dB OSNR
• 16QAM at 16.9 dB OSNR
Propagation at 37.5 GHz spacing with 1-1.5 dB OSNR margin
• 8QAM at 2400 km NZ-DSF
• 16QAM at 1200 km NZ-DSF
Results in line with state of art → no performance tradeoffs
