The new FIBERFOX Expanded Beam Fiber Optic Connectors from NEUTRIK are designed to meet the requirements of MIL-DTL-83526 specifications for deployment in harsh environments and use nonphysical contact fiber optic termini that are IP68 sealed behind an anti-reflective coated ball lens. This lens expands the beam to many times its original size aiding optical alignment and minimizing the effects of dust, debris, and other environmental conditions. The expanded beam fiber optic connectivity is exceptional in wet, dirty, dusty, high and low-temperature environments. These Connectors can be used in Lighting, Network, Broadcast, PA, Video, Defense, Railway, and Oil & Gas for Communications, Audio / Video, and Sensing Applications.


With 50/125 multimode fiber, the expanded and collimated light beam has an active area of around 3600 times larger than the original 50 μm multimode fiber core. Effectively maintenance-free with a theoretical unlimited lifetime, FIBERFOX can withstand in excess of 10,000 mating cycles without maintenance or insertion loss and can be cleaned using just clean water and a lint-free cloth. IP68 compliant certified waterproof up to a depth of 6m the connectors feature a screwed locking mechanism.
