摘要

本文对用于布里渊后向散射应变传感器的最新一代电信光纤进行了研究。来自5个不同制造商的30多种纤维已经测试了它们创建稳定和准确的应变传感器的能力。根据ITU-T(国际电信联盟)的标准，已经证明，属于同一标准的光纤，即使由一个制造商提供，也会表现出根本不同的布里渊后向散射响应。研究表明，单峰布里渊谱不能作为光纤选择的主要参数。为了获得准确和可重复的应变测量结果，有必要在激光脉冲宽度范围内对光纤进行初始检测。

Brillouin backscattering analysis in recent generation of telecom optical fibers

This paper reports on examination of the latest generation of telecom optical fibers for the Brillouin backscattering strain sensor application. Over 30 fibers from 5 different manufactures have been tested in terms of their ability to create a stable and accurate strain sensor. It has been proved that fibers that belong to the same standard, according to ITU-T (International Telecommunication Union), and even if provided by one manufacturer, demonstrate fundamentally different Brillouin backscattering response. It has been shown that unimodal Brillouin spectrum cannot be treated as the main parameter for fiber selection. In order to achieve accurate and reproducible results of strain measurement, it is necessary to perform initial examination of the fibers over the range of laser pulse width.
