空芯光纤进展Progress in Hollow Core Fiber Technology
➀ 文章讨论了空芯光纤与实芯光纤的优缺点。➁ 暨南大学在小尺寸空芯光纤方面取得了进展。➂ 文章提到了暨南大学、领纤科技以及其他实体在空芯光纤试验中的合作。➃ 试验使用了无节点反谐振结构，采用与微软3月份一样的三套管双反谐振结构，目前的最低损耗为0.11dB/km。➄ 传统光纤的非线性效应在空芯光纤中可以忽略，这对提高信噪比至关重要。➅ 2024年9月在苏州进行了试验，测试了损耗、色散、瑞利背向散射等指标，但没有进行系统传输验证。➆ 在ECOC2024上展示了使用三套管双反谐振结构的试验，光缆损耗为0.14dB/km，含连接损耗的光纤总体损耗为0.13dB/km。➀ The article discusses the advantages and disadvantages of hollow core fibers compared to solid core fibers.➁ Jilin University has made progress in small-size hollow core fibers.➂ The article mentions the collaboration between Jilin University, Lianxian Technology, and other entities for hollow core fiber trials.➃ The trial used a nodeless anti-resonant structure with triple-tube double anti-resonant structure, achieving a minimum loss of 0.11dB/km.➄ Traditional fiber nonlinear effects can be ignored with hollow core fibers, which is crucial for improving signal-to-noise ratio.➅ Trials were conducted in Suzhou in September 2024, testing loss, dispersion, and Rayleigh backscattering without system transmission verification.➆ ECOC2024 showcased trials with a triple-tube double anti-resonant structure, achieving a loss of 0.14dB/km for the cable and 0.13dB/km for the overall fiber.
