Plenum cables are specially built for plenum spaces, which are rarely-used or accessed spaces like those above ceiling panels or between walls. offers a variety of plenum-rated cables intended for safe use in your home or office space. 

In a few other blog entries, we've delved into what exactly a plenum cable is and what separates it from other cables. While you might not have heard the word until you began shopping for cables for your home or office data network, you've most certainly encountered plenum spaces before. Think of the "out of sight, out of mind" areas of buildings you frequently access. To put it simply, a plenum space is space within the building meant for things like wiring and HVAC installments, ductwork: think of the spaces above drop ceilings, below your flooring, or between the walls. Plenum spaces aren't intended for occupation or day-to-day use. Running cable through plenum spaces is ideal because it keeps cables out of sight, and away from any unintentional handling or movement that might interrupt their use. It also means that because these spaces can be difficult to access, cable being installed there should be sturdy and built to last, as replacing them would be a lot of trouble.

Our Category 6 Plenum Rated Shielded Ethernet Cables feature shielded construction in order to block EMI or electromagnetic interference, ensuring clean signal transmission. They're built with a CMP (plenum) 23 AWG jacket and operate at bandwidths of up to 550 MHz. The jacket is intended to comply with fire safety codes, which means that it's less likely to burn in the event of a fire, which will slow the spread of fire through those plenum spaces. While the jacket itself won't stop a fire, it won't emit toxic fumes as it burns.
