Development and Performance Evaluation of Non-slippage Optical Fiber as Brillouin Scattering-based Distributed Sensors

First, the internal slippage between bare fiber and coating material of current commercial fiber optic sensors (FOSs) has been, experimentally, verified and investigated in this article. Second, two types of effective package methods are proposed to develop non-slippage optical fibers. Finally, the performance of developed nonslippage FOSs are examined and evaluated with a series of experiments, and the thermal expansion coefficient and creep property of the packaged optical fibers are also investigated. The experimental results indicate that the packaged fibers can be used as non-slippage sensors with high sensing performance both on actual and virtual spatial resolution. Especially, the creep property is much more stable than that of the current commercial fibers.
