How Cable Aging Impacts Network Stability Over Time
We tend to think of network infrastructure as static. Once you pull the wire through the wall, punch it down, and plug it in, the assumption is that it will work forever. Unlike a hard drive with moving parts or a battery that loses its charge, a copper wire seems like a permanent fixture. However, Ethernet networking cables are subject to the same laws of physics and chemistry as everything else. They age. They degrade. And eventually, they fail. Cable aging is a silent killer of network performance. It doesn't usually happen overnight with a dramatic "snap." Instead, it is a slow creep. A network that ran at 10 Gigabits five years ago might struggle to negotiate 1 Gigabit today. Packets start dropping. PoE devices reboot randomly. Understanding the mechanics of cable aging—what causes it and how to prevent it—is essential for anyone managing a network that needs to last more than a few years. It is the difference between a "set it and forget it" install an...
