Fiber-Optic Perimeter Intrusion Detection by Employing a Fiber Laser Cavity in Each Defensed Zone

A fiber laser cavity was employed for the first time in fiber-optic multi-zone perimeter intrusion detection system. A length of four-core armored fiber cable was configured into multiple sections with each defensing a perimeter zone. For each defensed perimeter zone, only three single-mode fibers o...
