Real-time 80λ × 800 Gbps/carrier optical transmission system based on C6T + L6T band spectra with a transmission distance of 1050 km

We report a real-time 80λ×800 Gbps/carrier optical transmission system based on C6T + L6T band spectra and PCS-16QAM modulation format. The span loss is compensated only by the erbium-doped fiber amplifiers (EDFAs). The transmission performance of the 800 Gbit/s system based on G.654.E fiber and G.652.D fiber was tested and compared. The experimental results show that the 80λ×800 Gbps/carrier signals in G.654.E fiber and G.652.D fiber are able to transmit 1050 and 600 km, respectively, under standard span loss. The transmission distance of 1050 km, to the best of our knowledge, is the farthest transmission distance reported for the 800 Gbps/carrier system based on C + L band spectra under standard span loss, which provides guidance for the future optical network upgrade from 400 to 800 Gbit/s.

Abstract

We report a real-time 80λ×800 Gbps/carrier optical transmission system based on C6T + L6T band spectra and PCS-16QAM modulation format. The span loss is compensated only by the erbium-doped fiber amplifiers (EDFAs). The transmission performance of the 800 Gbit/s system based on G.654.E fiber and G.652.D fiber was tested and compared. The experimental results show that the 80λ×800 Gbps/carrier signals in G.654.E fiber and G.652.D fiber are able to transmit 1050 and 600 km, respectively, under standard span loss. The transmission distance of 1050 km, to the best of our knowledge, is the farthest transmission distance reported for the 800 Gbps/carrier system based on C + L band spectra under standard span loss, which provides guidance for the future optical network upgrade from 400 to 800 Gbit/s.
