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 OM4 "Purple" laser-optimized, multi-mode cable with a 50µm core and 125µm cladding diameter. The cable has a color-coded Dual LC connector on each end and is ideal for use in 10 Gigabit Ethernet (GbE) networks. The cable jacket is OFNR (Optical Fiber, Nonconductive, 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.
