Abstract

We demonstrate 25-GHz-spaced eleven-channel 171 Gb/s PDM 16-QAM transmission over 1440 km. 16-QAM signals were generated by high-speed digital-to-analog converters. We achieved a record spectral efficiency-distance product of 9216 b/s/Hz-km (6.4 b/s/Hz × 1440 km) in the 16-QAM format.

11 × 171 Gb/s PDM 16-QAM传输1440公里，使用高速DAC，频谱效率为6.4 b/s/Hz

我们演示了超过1440公里的25 ghz间隔11通道171 Gb/s PDM 16-QAM传输。16-QAM信号由高速数模转换器产生。我们在16-QAM格式下实现了创纪录的9216 b/s/Hz-km (6.4 b/s/Hz × 1440 km)的频谱效率-距离乘积。
