Ethernet Cables

Purchase or make your own Ethernet cables

Ethernet network cables connect computers to a wired network. Purchase Ethernet cables at a variety of network cable distributor websites and in bricks and mortar stores. A business that needs to build a new network, wire new construction for an Ethernet network, or just requires long Ethernet cabling may want to consider making Ethernet cables.

The ends of computer Ethernet cables, technically called RJ45 ends, are like those of the phone cable that plugs into your phone jack. They are designed to be easily wired by the end user. You'll need a few simple tools, including a wire stripper, a crimper designed for RJ45 ends, the RJ45 ends themselves and a spool of Ethernet cable. Even huge Ethernet cables are limited by effective length; each type of cable has a maximum length determined by the technology.

There are several types of Ethernet cable:

1. Cat5 Ethernet network cables support transmission rates of up to 100 Mbps.

2. Cat5 Enhanced, usually called Cat5e and currently the most commonly used, takes better advantage of all 4 pairs of wires it contains and thus provides transmission rates of 1000 Mbps for shorter cable length.

3. Cat6 provides performance that's best used for future-proof cable for new construction.

Learn to make Ethernet cables

There are limits to the length of the various types of cables. Some situations require such things as Ethernet crossover cables or Ethernet patch cables. You can purchase ready-made Ethernet cables, but it may be more economical and practical to make your own, especially if you need number of them or particularly long ones.

Purchase the supplies to make your own cables

Any store or website that sells computer supplies will have a regular network cable for sale, but a specialized network cable distributor will also carry big spools of cable and supplies to allow you to make those huge Ethernet cables.

Test your Ethernet cables

Any of the Ethernet cable distributors listed also sells cable testers. The method of constructing long Ethernet cabling is relatively straightforward, especially if you have read some network cables information, but it's always a good idea to test them and make sure they work properly.

• It's recommended that you don't make huge Ethernet cables of unlimited length; while you could physically make a cable longer than the maximum, it would not work correctly.
• Cat 6 and Cat 5e cables are backwards compatible with older cable standards, so you can use a Cat6 cable in a jack meant for a Cat 5e, and vice versa.
