Category 6 Plenum Patch Cables
To conform with local fire codes, it is often necessary to use category 6 plenum cables with a CMP jacket to help reduce the spread of fire should one break out. There is a lot of jargon and different jacket type ratings, but to be safe always look for CMP on the jacket. This is the highest level of in-wall and in-ceiling rated plenum wire. The reason why these are required is because it burns slower than regular Riser Rated Cable in case of a fire. All category 6 plenum patch cables manufactured and sold by Cables.com are 550Mhz rated, the fastest speed achievable! Although CMP may not be a better-quality cable than CMR, it is better to be safe when running new installations or just wiring existing environments. Please note that all plenum cables are built to order in 1-2 days and cannot be returned.
