What does Cat6 CMR mean?

Communications Multipurpose Cable, Riser
CMR cable stands for “Communications Multipurpose Cable, Riser”. It is a cable jacket fire resistance rating defined in Article 800 of the NEC. CMR cable is also referred to as “riser-rated cable” and designed to prevent fires from spreading between floors through risers or vertical shafts.

What does CMR rated mean?

A CMR rating means the cable can be used in the risers of commercial buildings because they limit the spread of flames better than cables in the CL/CM family. They can be installed anywhere except plenums. CL2R and CL3R are the riser versions of CL2 and CL3, meant to carry higher voltages.


If you want faster internet speeds, Cat6 is a good choice. It reduces something called “crosstalk” — signal transfers that disrupt your communication channels. If you are happy with your current internet speeds, however, Cat5 might be all you need. Besides, Cat5 cables tend to be cheaper than Cat6.

What does UTP CAT 6 mean?

unshielded twisted pairs
CAT6A U/UTP means the cable consists of 4 unshielded twisted pairs and no outer shielding. CAT6A F/UTP means the cable consists of 4 unshielded twisted pairs however it contains an outer foil shield. This is a shielded cable.

Is UTP cable plenum rated?

The cat6 plenum 1000ft UTP, CMP rated cable is perfect for air plenum spaces where the chances of a fire event are high. It has a thick CMP jacket which has a fire-retardant coating that makes it ideal for use in plenum spaces of residential and commercial properties.

What is UTP Ethernet cable?

Unshielded twisted pair (UTP) is a ubiquitous type of copper cabling used in telephone wiring and local area networks (LANs). There are five types of UTP cables — identified with the prefix CAT, as in category — each supporting a different amount of bandwidth.

What is better UTP or FTP?

Advantages of U/FTP over F/UTP Better Performance – When installed correctly, the U/FTP cables provides superior crosstalk and EMI performance. Crosstalk is when the signal in one twisted pair interferes with the signal in another twisted pair.

Is UTP the same as RJ45?

The regular connector for the UTP cable is called an RJ45.

Can UTP cable be used outside?

Exterior-grade Ethernet cables are waterproof and can be buried in the ground without a conduit. If you aren’t burying the cable, choose a waterproof Cat 6 cable that has a UV protective jacket to prevent damage from sunlight exposure. This is important when running the cable up the side of a house or across a roof.
