Strict building code requirements for cabling in plenum spaces have created installation challenges in settings such as schools, hospitals and other commercial buildings. Previous solutions were limited to "over Cat5/6" products, which added to both the complexity and the reliability of the installation due to the need for power and signal conversion. C2G, formerly Cables To Go, has expanded its connectivity portfolio to include a line of commercial grade plenum cables that are ideal for routing audio/video cables through plenum space above dropped ceilings or under raised floors.
