Cablesys high density, HD, fiber optic LC to LC patch panel is designed for backbone-to-backbone and backbone-to-horizontal fiber cabling and support single mode SM fiber optic networks. The LC-LC fiber patch panel is preloaded with 24 LC quad adapters that can accommodate up to 96 fibers. The adapters are loaded onto a 16 gauge steel frame that is black powder coated to protect against wear, corrosion, impact and weather. Each fiber optic LC adapter, also known as coupler, is built with a metal sleeve for precision alignment and longevity, and it can be used for up to 500 matings. The LC couplers are made from durable UL 94V-0 and polyethermide material colored blue, which is recommended for singlemode Ethernet networking. Each LC coupler comes with a protective cap to prevent dust and debris from entering. CBS patch panel fits on racks and cabinets with 19 inch mounting widths and takes up 1 rack mount space, 1 RMS.
