在这项工作中，我们提出了一个实时跨洋空分复用传输耦合芯多芯光纤的实验演示。为了补偿耦合芯多芯光纤中的模式耦合，我们基于现场可编程门阵列电路实现了实时多输入多输出（MIMO）数字信号处理。使用具有实时MIMO的光接收器，我们演示了超过7200 km的16通道波分复用耦合四芯光纤传输。结果表明，实时耦合芯多芯光纤传输的可行性。
In this work, we present an experimental demonstration of real-time transoceanic space-division multiplexed transmission with coupled-core multicore fibers. To compensate for modal coupling in the coupled-core multicore fibers, we implement real-time multiple-input multiple-output (MIMO) digital signal processing based on field programmable gate array circuits. Using optical receivers with a real-time MIMO, we demonstrate 16-channel wavelength-division multiplexed coupled four-core fiber transmission over 7200 km. The results show the feasibility of real-time coupled-core multicore fiber transmission.
