While most network equipment is easy to replace, cabling is not.
Switches, routers, access points, and IP phones can be upgraded as technology changes. But copper cabling is often installed behind walls, above ceilings, inside conduits, and across patch panels, where it may remain in place for decades. That makes the choice of cabling category more than a technical detail. It is an infrastructure decision that can affect performance, reliability, upgrade paths, and long-term cost.
In this article, we take a closer look at what copper cabling categories mean, how they affect network performance, and how installers, resellers, and consumers can choose the right cabling for their needs.
