Riser cable is cable that is ran between the floors in non plenum areas. They get their name because of the way riser cable is ran which is rising up to each floor. Riser cable is important in that it is a buildings backbone that transmits data, audio and video signals.

Riser cable is also seen as CMR which stands for communications riser. CMR is the fire retardant rating on riser cable which gives it the ability to be put in the walls. The common materials you can find in these cables jackets are flame retardant pvc and the insulation of Polyolefin (PO). These types of compounds help the cable against the spread of flame and performance at higher temperatures.

This type of cable is going to be the one majority of households install inside the walls of their homes. It can be ran floor to floor and also be used for general purposes like computer to switch, router and more. It is great for long runs which you want when you put in risers or walls because the majority of these cables are going to have solid conductors. Riser cable can connect to RJ45's and Keystone Jacks. An example of a riser cable channel usually has riser cable connected to keystone jacks then from the jacks a patch cord is connected to your end device.
