The interaction of Electromagnetic Pulse with buried Armoured Fiber Optic Cables

Abstract: The use of fiber optic cables is rapidly increasing all over the world with the advantages such as reliable, economic and high data transmission, low weight and wide bandwidth. However, due to its fragile and sensitive structure, the protection and performance of fiber optic cable can be a problem in some harsh environments such as underground and underwater. Thus, armoured fiber optic cables are designed to solve this problem. With the addition of steel wire or galvanized steel and aluminium tape layers, the fiber optic cables become durable and reliable for underground applications. In this study, the effect of a high intensity of an electromagnetic pulse on armoured fiber optic cable is considered. With steel tape/wire layer, the armoured fiber optic cable is considered as a cylindrical shell and analytical calculations carried out via a matrix model.
