Amphenol Fiber Systems International MIL-ST Fiber Optic Connectors are specially designed for deployable and fixed communication systems. These connectors meet the stringent requirements of MIL-C-83522 to provide the best possible optical performance in harsh environments. The MIL-ST series features a higher spring force than commercial ST connectors, enabling them to meet the shock and vibration requirements of MIL-C-83522. Stainless steel construction delivers mechanical strength and corrosion resistance. The boot is attached either by a compression ring or by a threaded adapter.
