Cables are essential in our technology-driven world. But not all understand the basics of residential or commercial computer network cabling. Now that most people are working from home, having a well-structured computer network is a must. So how do you do that? Let us first discuss the basics.

  1. A key component in wired home networks nowadays is the twisted-pair Ethernet cable. Twisted-pair Ethernet cables are used to connect DSL/cable routers or modems to computers, DSL/cable routers or modems to wireless access points, DSL/cable routers or modems to hubs or switches, computers to hubs or switches, and computers to other computers.
  2. Twisted-pair Ethernet cables consist of eight copper insulated wires in a plastic sleeve. Two wires are twisted together in a pair for a total of four pairs, and then the four pairs are twisted together to form the cable. A clear plastic jack, known as an RJ-45 connector, is attached to both ends of the twisted-pair Ethernet cable.
  3. There are several categories of twisted-pair cabling, but only three that are commonly used for Ethernet networks:

    • Cat5: Supports speeds up to 100 Mbps at 100 MHz, with a maximum cable length of 328 feet (100 meters).

    • Cat 5e: Supports speeds up to 1,000 Mbps (or 1 Gbps) at 100 MHz, with a maximum cable length of 328 feet (100 meters).

    • Cat6: Supports speeds up to 1,000 Mbps (or 1 Gbps) at 250 MHz, with a maximum cable length of 295 feet (90 meters).

  4. Twisted-pair Ethernet cables come in standard lengths such as 3, 5, 7, and 10 feet. Longer lengths are available, and you can also have custom cable lengths made. The distance between your various network devices and your network switch or router will determine the length you need. Don’t forget to include enough length to run cables along walls, under rugs, and around corners as necessary.
  5. Twisted-pair Ethernet cables come in all sorts of colors. This decision can be based purely on your individual tastes and preference. Blue is perhaps the most common, but you might also consider white, gray, or some other color that doesn’t clash with your walls and carpet.
