Ethernet Cable
Cabling · Beginner
Twisted-pair copper cabling used for Ethernet links, commonly four pairs with RJ45 connectors. Categories such as 5e, 6, and 6a support different speeds and distances.
The twists reduce interference. The printed category tells you what the cable was built to carry, but the terminations, length, and port settings also decide whether a speed actually works.
Example: A 25-meter Category 6 run links a desk to a closet and negotiates a 1 Gbps full-duplex connection.
Common misconception
- The plastic clip and connector do not identify the cable category. The jacket printing does.
