Explanation
Plenum cabling is specifically designed for installation in the plenum spaces of buildings-the air-handling areas above drop ceilings and below raised floors used for HVAC airflow. Building codes (such as NEC in the US) require plenum-rated cable in these spaces because standard PVC cable jackets release toxic fumes when burned. Plenum cable uses materials like FEP (fluorinated ethylene polymer) that produce minimal smoke and non-toxic gases. USB 3.1 Gen 2 is an interface standard for connecting peripherals. Straight tip (ST) fiber connectors are used in fiber optic networking but are not space-specific. Cat 8 is a high-speed Ethernet cable standard but is not restricted to commercial environments.
