Plenum Category 5e Ethernet


Cat5e Plenum-Rated Ethernet Cables

Category 5e Plenum Cables (CMP) are needed when your project requires that you run ethernet cables through ceilings or crawl spaces. Cat5e Plenum Cables conform to many local fire codes. They are also used in Digital Lighting Management Systems, to control lighting fixtures remotely. There is a lot of jargon and different jacket type ratings, but to be safe always look for CMP (Communications Multipurpose Cable, Plenum) 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 plenum cables manufacturered and sold by are 350Mhz rated, the fastest speed achievable!

Category 5e Plenum Cable Specifications:

  • 24awg Pure Copper
  • Never CCA
  • 350Mhz Rated
  • Gigabit Rated
  • POE (Power over Ethernet) Compatible

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.
