Beyond the Spec Sheet: What Network Engineers Actually Look for When Choosing Ethernet Cables
For the average consumer, choosing an Ethernet cable is often a simple matter of matching a color or a price point. But for a network engineer—someone whose reputation and career depend on designing and building fast, stable, and secure networks—the selection process is far more rigorous.
