These tactical Camplex assemblies feature QPC's QMini Expanded Beam Fiber Optic Connectors, designed to meet the requirements of MIL-PRF-83526/20 & /21 Military Specifications. Designed for harsh environments, Expanded Beam fiber optic connectors use non-physical contact fiber optic termini that are fully sealed behind an anti-reflective coated ball lens. By expanding the beam to a large size, this lens enhances optical alignment and minimizes dust, debris, vibration, and other environmental effects. Since the optical surfaces / end faces of the termini do not wear during use, the QMini connector is incredibly durable, with more than 3,000 mating cycles. Available in Single Mode and Multimode, in 2 or 4 Channels and a variety of lengths.
