Tripp Lite's 25-foot Plenum Rated SVGA cable is ideal in Educational or Commercial installations where local fire codes call for a CMP rated cable to run through walls, ceilings, and plenum air chambers. QXGA resolution is achieved through high quality construction: 75ohm Coaxial conductors for Red, Green, and Blue (RGB) signals, each protected by a 93% tinned copper braid shield. An overall shiled of Mylar foil and 85% Copper Braid shield ensures maximum signal integrity.
