摘要

【目的】

在电力与光通信网络融合场景中，光纤复合架空地线（OPGW）面临的雷击电磁干扰已成为制约系统可靠性的关键技术瓶颈。当OPGW光缆遭受雷击时，雷击引发的瞬态电磁干扰会导致光信号偏振态（SOP）产生剧烈波动。此类波动一旦超出接收端偏振跟踪模块的容限范围，将导致信号SOP恢复失准，显著提升误码率（BER），严重时可引发通信链路中断。有效抑制此类电磁干扰已成为提升系统可靠性的关键技术挑战。

【方法】

文章提出以反谐振空芯光纤（AR-HCF）替代常规实芯光纤作为OPGW光缆的核心传输介质，重点研究雷击作用下光SOP的演变机制。通过构建对照实验平台，将AR-HCF与单模实芯光纤置于等效雷击环境（峰值电流62.8~65.2 kA，波形10/350 μs），同步对比观测两者SOP的动态响应差异。

【结果】

实验表明：AR-HCF凭借低介电常数空气波导结构，有效抑制了雷击电磁场的耦合效应，其偏振态旋转（RSOP）稳定在0.1~0.2 krad/s区间内，波动幅度远低于常规实芯光纤（后者RSOP波动范围达1~15 krad/s）。

【结论】

文章明确了雷击电流幅值-时间特性与RSOP的关系，以及AR-HCF的偏振参数（

）与实芯光纤的定量关联规律，实验结果表明，使用AR-HCF的OPGW光缆电磁耦合得到抑制，SOP更稳定，该研究为新一代抗雷击OPGW光缆的智能监测系统研发及光缆成本控制提供了理论支撑和新的方向。

Abstract

【Objective】

In the integration scenario of power and optical communication networks

the lightning electromagnetic interference faced by Optical Fiber Composite Overhead Ground Wire (OPGW) has become a key technical bottleneck restricting the system reliability. When the OPGW cable is struck by lightning

the transient electromagnetic interference caused by lightning will cause the State of Polarization (SOP) to fluctuate violently. Once such fluctuations exceed the tolerance range of the polarization tracking module at the receiving end

it will lead to inaccurate recovery of the signal SOP

significantly increasing the Bit Error Rate (BER). In serious cases

it can cause communication link interruption. Therefore

effectively suppressing such electromagnetic interference has become a key technical challenge to improve the system reliability.

【Methods】

This research proposes to replace the conventional solid-core fiber with Anti Resonant-Hollow Core Fibers (AR-HCF) as the core transmission medium of OPGW cable

and focuses on studying the evolution mechanism of optical SOP under lightning action. By constructing a control experiment platform

the hollow-core fiber and the single-mode solid-core fiber are placed in an equivalent lightning strike environment (peak current 62.8~65.2 kA

waveform 10/350 μs)

and the dynamic response differences of the SOP of the two are synchronously observed and compared.

【Results】

The experiment shows that the AR-HCF with the help of its low dielectric constant air waveguide structure

can effectively suppress the coupling effect of the lightning electromagnetic field. Its Rotation of State of Polarization (RSOP) is stable in the range of 0.1~0.2 krad/s

and the fluctuation range is much lower than that of the conventional solid-core fiber (the latter's RSOP fluctuation range reaches 1~15 krad/s).

【Conclusion】

The article clarifies the relationship between the amplitude-time characteristics of lightning strike current and polarization state rotation

as well as the quantitative correlation rules between the polarization parameters (S

) of AR-HCF and those of solid-core optical fibers. The experimental results show that the electromagnetic coupling of the OPGW cable using the AR-HCF is suppressed

and the SOP is more stable. This study provides theoretical support and a new direction for the development of intelligent monitoring systems for the new generation of lightning-resistant OPGW cables and for cost cont

rol of the cables.
