报道了32路归零（RZ）/正交幅度调制信号在10 Gsymbol/s × 8光时分复用（OTDM）下的单载波800 Gb/s相干传输。通过在相干接收机中采用RZ连续波转换方案，实现了225 km以上的传输，这使得能够以高信噪比解调和解复用超高速多级OTDM信号。
We report the single-carrier 800-Gb/s coherent transmission of polarization-multiplexed 32 return-to-zero (RZ)/quadrature amplitude modulation signals at 10 Gsymbol/s × 8 optical time-division multiplexing (OTDM). Transmission over 225 km was achieved by adopting an RZ-continuous-wave conversion scheme in a coherent receiver, which made it possible to demodulate and demultiplex ultra high-speed multilevel OTDM signals with a high signal-to-noise ratio.
