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. 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.The new Pro Series commercial grade plenum cables offer true digital performance while meeting the highest standards in fire resistance. Available for HDMI, DVI and DVI+3.5mm audio signals, these cables can meet the demands of virtually any commercial installation.
