FiSens® FBG Sensor Chains

FBG Sensor Chains for use with FiSpec Interrogators

The FiSens® FBG Sensor Chain is a spliceless chain of multiple high-precision FBG sensors “written” into a single SM800 fiber. When the sensor is paired with a FiSens® interrogator offers a multipoint, distributed sensing solution for temperature or strain measurements. The FBG sensor chains utilize a unique fentosecond (fs-Laser) Laser Inscription method offering an innovative FBG-based solution with best performance together with lowest cost per sensor point on the market.
