Paper Abstract

This paper will discuss a new distributed fiber optics sensing technology that uses an array of low reflectivity fiber gratings having the same center wavelength. Furthermore this array would be embedded in a military grade reinforced outdoor cable. Three of these gratings cables are to be stitched onto a meter high geo textile and used as a solution for landslides warning. The special cable is made with a material that prevents moisture penetration and provides extra pulling strength of up to 500 Newtons. The geo-textile provides the added restraining force of up to 1100 Newtons. The solution is therefore capable of not only measuring small earth movements but also provides added time delay in a pending crisis so that people can evacuate from danger.
