我们演示了一种新的1.2-Tb/s NGI-CO-OFDM超级信道的产生,包括24个频率锁定的12.5-GHz的PDM-QPSK载波,并通过72×100-km的超大面积光纤传输,实现了3.7-B/s/Hz的信道频谱效率(SE)和27,000-km·B/s/Hz的记录SE距离积。
We demonstrate the generation of a novel 1.2-Tb/s NGI-CO-OFDM superchannel comprising of 24 frequency-locked 12.5-GHz spaced PDM-QPSK carriers, and transmit it over 72×100-km of ultra-large-area fiber, achieving 3.7-b/s/Hz channel spectral-efficiency (SE) and a record SE-distance product of 27,000-km·b/s/Hz.
