Abstract: A new fiber optic cable splice for splicing optical fiber cables together and reconstructing fiber-optic cable that provide substantially enhanced reliability and broadened operating temperature range is disclosed. The disclosed cable splice offer reliable and user friendly solutions to applications in many harsh environments such as avionics, field vehicles, and defense related instrumentation. The cable splice consists of a preassembled one piece splice core and outer mechanical and thermal shielding layers. A simple splicing procedure and key fixtures are also disclosed.
Abstract: An fiber optic splice having substantially enhanced reliability and broadened operating temperature range uses a light-cured index matching fluid to splice the facing ends of the optical fibers in between two metallic tubes forming a leak-tight, thermally insulating, and mechanically robust outer package.
