摘要

我们报告了使用四个80- g采样/s 32.5 ghz带宽adc和32-QAM减少保护间隔CO-OFDM的单个相干接收器检测到创纪录的606-Gb/s数据速率(503-Gb/s，不包括20.5%的fec开销)。以7.76-b/s/Hz的信道内净频谱效率传输信号。

Single coherent detection of a 606-Gb/s CO-OFDM signal with 32-QAM subcarrier modulation using 4×80-Gsamples/s ADCs

We report the detection of a record 606-Gb/s data rate (503-Gb/s excluding 20.5%-FEC-overhead) by a single coherent receiver using four 80-Gsamples/s 32.5-GHz-bandwidth ADCs and reduced-guard-interval CO-OFDM with 32-QAM. Transmission of the signal with 7.76-b/s/Hz net intrachannel spectral efficiency is demonstrated.
