Are you having trouble deciding between riser-rated and plenum-rated cables because of an ignorance problem? If so, do not fret and take the time to read this article thoroughly and then make an educated choice. Both cables for plenum and riser are available in every variation, such as Cat5e Riser and Plenum, Cat6 Riser and plenum, and Cat6a Riser and plenum.
Plenum and riser-rated cables are two kinds of communication cables widely used in offices and computer rooms. They are primarily used in telecommunication and LAN industries. But before you make use of them, you should know the differences between these two cables and when to use each. This blog will tell you all about these cables.
What is a Riser Cable?
A cable that bears a “CMR” or “CMR” mark on its jacket is riser-rated. CMR is a shorthand for Communications Multipurpose Cable or Riser. Their jackets are constructed from high-quality polyvinyl chloride (PVC).
These cables are designed to be used in the riser spaces in structures. But, due to the high-quality jacket material, you can also utilize a cable rated for risers for outdoor applications; however, it cannot be reversed. Cat5e, Cat6, and Cat6a are among the most popular cable types with a riser rating.
What Is Plenum Cable?
An ethernet cable with a “CMP” mark on its jacket is a plenum cable. CMP is the abbreviation as Communications Multipurpose Cable, Plenum. It is essential to point out that CMP is a CMP score considered the top quality fabric of the jackets on ethernet cables. As the name implies, the cables are utilized to be installed in the plenum areas of the structures.
Plenum spaces are empty spaces between ceilings and floors that function as air circulation channels. Because the air circulation here is more significant and the oxygen is present in an excellent ratio, it is possible to have a fire outbreak in these spaces. If the fire starts in any of the structures, the plenum space can act as a way to help spread the flames faster. To combat this, the installation of plenum-rated cables in these areas.
These cables are fire-retardants, thus halting flames’ progression. In addition, when exposed to flame, these cables don’t emit dangerous gasses or elements. They are also UV-resistant. Because of the superiority of CMP-rated Ethernet cables, they can be utilized outdoors and risers. However, it isn’t reversed.
What is “Cat” mean?
The Cat refers to the Category, and the numerical value is the generation. For example, the Cat5e is the 5th generation Ethernet cable, while Cat6 is part of the 6th generation. The most current generation offers higher bandwidth capabilities, data transfer rates, and protection from crosstalk and EMI.
Plenum or Riser: Which Cable is Best For You?
It is based on only one thing: the building’s area where you will put the cable. For instance, when you install Ethernet cables in the plenum areas of buildings, you’ll need to install a plenum-rated cable (Cat5e Plenum cable Cat6 plenum cable Cat6a Plenum cable).
If you plan to put the Ethernet cable in the spaces that arise in the buildings, you’ll require a riser-rated cable, one with a CMR symbol on the outside face of the jacket.
Specifications Comparision
When it comes to the specifications of the cables are concerned, they are identical. For example, the Cat5e Riser Cable and a Cat5e Plenum Cable will share the same bandwidth capabilities and speeds for data transfer additionally, since both cables feature thick coatings that protect against any crosstalk such as close-end crosstalk (NEXT) and alien-crosstalk (AXT) as well as electromagnetic interference (EMI) which keeps the quality of signal and the integrity of data in good condition. One thing that sets each cable distinct is its jacket materials.
Although you can utilize a plenum-rated cable in riser spaces, it has an issue that plenum-rated cables tend to be significantly more expensive than riser-rated cables. There’s no reason to pay more for a cable if you have a choice available.
Regarding the standards for these cables areas, they are concerned that both plenum and riser Ethernet cables comply with FCC, CE, CSE ISO/IES and conform to RoHS and TIA/EIA standards. Additionally, these cables can be used in harsh environments without compromising the integrity of data.
Conclusion:
This article covers everything you must know about riser and plenum ethernet cables. We hope this article has given you the information you need.
When choosing which cables to purchase for your home or business, it can be hard to know which one to go with. There are a lot of different factors to consider, including the cable’s safety rating, the material, and the length. We hope this blog has helped you understand the importance of choosing the right cables for your needs and that you’ll contact us anytime if you need help!
