We present the fabrication and characterization of a low-loss enhanced backscattering fiber, having the core doped with MgO-based nanoparticles (MgO-NP), for distributed sensing application. The fiber has a scattering increment of 48.9 dB and two-way attenuation of 14.3 dB/m; these are the largest Rayleigh scattering increment paired with the lowest losses for this type of fiber. In this work, we provide a thorough characterization of the fiber performances, and their impact on distributed sensing networks, using scattering-level multiplexing where a 2.4 – 4.0 times extension of sensing length can be achieved.

我们提出了一种低损耗的增强反向散射光纤的制造和表征,该光纤的纤芯掺杂有基于MgO的纳米粒子(MgO-NP),用于分布式传感应用。光纤的散射增量为48.9 dB,双向衰减为14.3 dB / m。这些是此类光纤最大的瑞利散射增量和最低的损耗。在这项工作中,我们使用散射级多路复用技术对光纤性能及其对分布式传感网络的影响进行了全面的表征,可以将传感长度扩展为2.4 – 4.0倍。
