Choosing the right Ethernet cable depends on where it will be installed. When comparing plenum vs riser Cat6, the main difference is the cable jacket's fire-safety rating and intended location. Plenum-rated cables are designed for designated air-handling spaces, while riser-rated cables are intended for vertical runs between floors. Both can support reliable Gigabit Ethernet when installed correctly. I recommend checking local building codes and project requirements before making a decision. TS Cables offers networking cable options for customers across the USA. Understanding these differences helps installers choose suitable cabling for safety, performance, and long-term network reliability.
