Because of its immunity to electronic interference and its greater speeds over longer distances; fiber optic cabling has become the conduit of choice for high speed network communications. Monoprice is proud to offer a full line of high-quality Single-mode and Multi-mode duplex cables using optical fibers made by Corning. This is an OM3 "Aqua" multi-mode cable with a 62.5 μm core and 125 μm cladding diameter. The cable has a pair of color-coded ST connectors on one end and a Dual LC connector on the other end. The cable jacket is OFNR (Optical Fiber; Non-conductive; Riser) rated by UL; which means that it complies with fire safety and insurance requirements and is safe for use within the walls; and between the floors; of commercial class buildings.
