Security, defense and sensing applications often require routing of optical fibers through constrained spaces. Fibers or fiber cables must frequently be tightly matched or mounted onto structures having arbitrary shapes or forms, which inevitably leads to requirement for tight fiber bends. In such case macro bend loss presents one of the major concerns and limitations in practical applicability of optical fibers. Fibers with high bend tolerance are therefore required in such environments. To date, significant works relating to the understanding and improvement of bend-loss sensitivity have been carried on for single-mode fibers and fiber systems. However, in security and defense applications, robust connectivity and installation reliability issues often favor multimode fiber systems.
