Abstract

We demonstrate 2688-km multi-span transmission using wavelength-division multiplexing (WDM) of ten 50-GHz spaced 128-Gb/s PDM-QPSK signals, space-division multiplexed (SDM) in a low-crosstalk 76.8-km seven-core fiber, achieving a record net aggregate per-fiber-spectral-efficiency-distance product of 40,320 km·b/s/Hz. The demonstration was enabled by a novel core-to-core signal rotation scheme implemented in a 7-fold, synchronized recirculating loop apparatus.

摘要

我们展示了使用十个间隔为50GHz的128Gb/s偏振复用正交相移键控（PDM-QPSK）信号进行波分复用（WDM）的2688公里多跨距传输，这些信号在低串扰的76.8公里七芯光纤中进行空分复用（SDM），实现了创纪录的每光纤光谱效率距离乘积40320公里·比特/秒/赫兹。该演示通过在一个7倍同步循环回路装置中实施的新型芯间信号旋转方案得以实现。
