MFOCA Mining Fiber Optic Connectors


Based on Stran Technologies’s TFOCA GenX tactical fiber optic connector, the MFOCA provides the ultimate in reliable performance for harsh environments. It is hermetically sealed to exclude moisture in wet environments and certified for use in hazardous areas. Built on the well proven 2.5 mm ceramic ferrule technology, the design and packaging of these connectors provide a robust connectivity solution resistant to corrosion, mechanical damage and potentially explosive environments, while providing reliable operation and ease of field maintenance.  Rated as explosion-proof, the receptacle prevents flame propagation into and out of an XP-rated cabinet.
