FBG is a core element used as a sensor for structure health monitoring. The tight buffer FBG array consists of FBG array sensors. The outer layer could be material of PVC, nylon or hytrel which protects the FBG sensors and ruggedizes the construction. 

The fiber optic buffer array is designed to make handling and installation fast, easy and intuitive. It delivers the many advantages inherent to all FBG based sensors while elevating the degree of ruggedness to be consistent with, if not exceeding, industry expectations.
