Which cable type emits minimal smoke and is used when fire safety is a priority?

Plenum-rated cables are designed to emit minimal smoke and reduce harmful toxic fumes in the event of a fire, making them ideal for use in spaces like air ducts and areas with high occupancy. These cables are constructed with fire-resistant materials that limit the spread of flames and prevent the release of noxious substances. In environments where fire safety is a priority, such as office buildings and schools, the installation of plenum-rated cables is often required by building codes because they improve safety for occupants and first responders.

In contrast, other cable types such as Cat 6 and Cat 8 cables may not have these specific fire safety features, as they are generally designed for high-speed data transmission rather than for enhanced fire safety. Non-plenum-rated cables are typically less expensive but can produce more smoke or toxic gases if ignited, making them unsuitable for the same applications as plenum-rated cables. This ensures that in critical applications where safety is paramount, plenum-rated cables are the preferred choice.
