How To Make Ethernet Cables

Wireless and powerline networking can not compare in reliability to good-old fashioned Ethernet cables. They are also not too expensive or difficult to make. To start off, you will need some tools and hardware.

Ethernet cables are made out of four twisted wire pairs giving a total of eight wires. For standard 10/100 based communications, only four wires are actually used for transmitting and receiving signals. All eight wires are used for 1000 Mbps or Gigabit Ethernet. Cat5, Cat5e, and Cat6 are the most popular forms of Ethernet cable. Cat5 has a typical bandwidth of 100 MHz and it is not recommended for use above 10/100 Mbps. Cat5e can be used for gigabit Ethernet and has a typical bandwidth of 350 MHz. Last, but not least, is Cat 6 which also transmits Gigabit Ethernet, and has a typical bandwidth of 500 MHz or higher.

Below is a pinout diagram for a standard 10/100/1000 based Ethernet cable. The pinout diagram should only be used for Ethernet cables connecting computers to networking devices such as routers, switches, or cable modems. Do not use this pinout for computer to computer connections where a crossover cable would be necessary.
