How to Make a LAN Cable

How to Make a LAN Cable

Most of us who’s hobby is assembling or tinkering computer don’t bother to acquire knowledge on LAN cabling, simply because LAN cable is readily available and can be bought at any computer store. There is nothing wrong in buying ready-made LAN Cable. The problem is, we can’t always find the right length for our needs and it is quite expensive.

Here, we will learn how to make a LAN Cable. There are two types of LAN Cable: the Straight and the Crossover Cable. What is the difference between Straight Cable and Crossover Cable? The Straight cable is used to connect computers to hub or switch while the Crossed Cable is use to Connect two computers directly without using any hub or switch provided that both computers have LAN cards. The materials we will use are: Registered Jack 45 (RJ-45) and an unshielded twisted pair (UTP). Category 5e is recommended if the speed of your network is running at speeds up to 1000 Mbps (1 gigabit per second). The only tool we will use is RJ45 crimping tool.


The first type of cable we’re going to make is a straight cable. First, take a desired length of cable, strip off the cladding using the stripper of the crimping tool, exposing the eight conductor wires, then arrange the wire as follows: white with orange, orange, white with green, blue, white with blue, green, white with brown, brown. After you arranged the wire, insert the wires to the RJ45. The white with orange wire goes to the Pin 1, the orange wire in Pin 2, the white with green wire in Pin 3, the blue wire in Pin 4, the white with blue in Pin 5, the green wire in Pin 6, the white with brown in Pin 7 and lastly the brown wire in Pin 8. After you insert the correct color of the wire in the RJ45, crimp it using the crimping tool. Next, repeat the procedure on the other end of the cable. Now we are done making a straight cable.

Let’s proceed with the crossover cable. The crossover cable has the same Pin configuration as straight cable at one end of the cable but the other end has a different Pin configuration. First, arrange the wire like in the straight cable then crimp it, then at the other end of the cable arrange the wire as follows: white with green in Pin 1, green in Pin 2, white with orange in Pin 3, white with brown in Pin 4, brown in Pin 5, Orange in Pin 6, blue in Pin 7, and white with blue in Pin 8. After the arranging the position of the conductor wires to the RJ45, crimp it. Congratulations! We now have completed making our two types of cables.
