Abstract

A novel fiber sensing algorithm is proposed and demonstrated, where two single-mode fibers is used to sense the same signal with different sign so that sensitivity is doubly enhanced and common noise is eliminated. High sensing resolution and high sensing dynamic may be achievable when the high encircling number and high-speed power detector are applied.
