Why would a technician use plenum-rated cables when installing new cabling in a datacenter?
Allows the cabling to be bent at sharp angles without snapping
Ensures an intruder cannot wiretap the cabling
Reduces hazardous fumes in the event of a fire
Efficiently reduces EMI and crosstalk in STP cabling
Plenum-rated cables have a special jacket made of fire-retardant materials. In the event of a fire, this jacket is designed to burn slowly and produce minimal amounts of smoke and hazardous fumes. This is a critical safety feature for cables run in plenum spaces, which are areas used for air circulation (like the space above a drop ceiling), as it helps prevent the spread of fire and toxic smoke throughout a building via the ventilation system.
