The cover illustrates an artistic impression of wavelength-division multiplexed data transmitted over the length of a hollow-core nested antiresonant nodeless fiber. In article number 2100102, Yang Hong and co-workers demonstrate the longest intensity-modulation direct-detection (IM-DD) transmission experiments (>100 km) achieved in a hollow-core fiber. This achievement represents ∼31% latency reduction as well as approximately five times transmission reach extension compared to a standard single-mode fiber. This work offers new insights into the realization of simple, cost-effective, high-capacity, ultra-low-latency IM-DD transmission links with the potential to revolutionize optical networks in the years to come.

空心光纤：空心光纤中超过 100 公里距离的低延迟 WDM 强度调制和直接检测传输（激光光子学修订版 15(9)/2021）

封面展示了波分复用数据在空心嵌套反谐振无节点光纤长度上传输的艺术印象。在文章编号 2100102 中，Yang Hong 及其同事展示了在空芯光纤中实现的最长强度调制直接检测 (IM-DD) 传输实验（>100 公里）。与标准单模光纤相比，这一成就代表了大约 31% 的延迟减少以及大约 5 倍的传输范围扩展。这项工作为实现简单、经济高效、高容量、超低延迟的 IM-DD 传输链路提供了新的见解，有可能在未来几年彻底改变光网络。
