Plenum-rated data cable is derived from an old HVAC term referring to “plenum spaces”.  A plenum space is the division of a building that facilitates air circulation by providing pathways for heated/air-conditioned and return air-flows at a higher pressure than typical.

Simply put, plenum-rated low-voltage data cabling services have an extra fire retard applied to the shielding portion of the cable making it more resistant to heat and less likely to cause fires vs. non-plenum cable which does not have this extra layer of fire protection.

The choices of On-site IT Services available for different cable products these days are very abundant. Every day new options are being introduced into the electrical market. Whether it be from the parameters changing to the different variations, the choices are becoming more and more plentiful as time goes on. One option; however, which is usually the first thing a person takes into consideration when purchasing cable remains pretty constant.
