What consideration should be taken for Ethernet cables that are installed in plenum areas?
What will be an ideal response?
Normally, the plastic covering of a cable is made of PVC (polyvinyl chloride), which is not safe when used inside plenums (areas between the floors of buildings). In these situations, plenum cable covered with Teflon is used because it does not give off toxic fumes when burned. Plenum cable is two or three times more expensive than PVC cable.
