Monoprice 11856 40M Single Mode Fiber Optic Cable LC/SC

The Monoprice 11856 is a 40-meter single-mode duplex fiber optic cable designed for longer-distance network connections in commercial and enterprise environments. Featuring LC connectors on one end and SC connectors on the other, it serves as a bridge between equipment with different fiber interface types—a common requirement when connecting newer switches or media converters (typically LC) to older patch panels or equipment (typically SC). The 9/125-micron single-mode construction supports high-bandwidth transmission over distances well beyond what copper cabling can achieve, making it suitable for inter-floor risers, long horizontal runs, and connections between network closets.

Built with Corning brand optical fibers, this cable delivers the signal quality and consistency that network professionals expect for permanent infrastructure. The yellow OFNR-rated jacket is UL listed for riser applications, meaning it can be safely routed within walls and between floors of commercial buildings in compliance with fire safety codes and insurance requirements. As a fiber optic cable, it is completely immune to electromagnetic and radio-frequency interference, which makes it an excellent choice for installations near elevator shafts, electrical panels, or manufacturing equipment where copper cabling would be susceptible to signal degradation.
