Making Ethernet Cables - Tricks of the Trade

purchasing-ethernet-cables-can-be Purchasing Ethernet cables can be quite expensive and pre-made lengths are not always the length you need. Making Ethernet cables is easy with a box of bulk Category 5e Ethernet cable and RJ-45 connectors that are attached to the cut ends of your preferred cable length.

Straight Through Cables

STRAIGHT THROUGH Ethernet cables are the standard cable used for almost all purposes, and are often called "patch cables". It is highly recommend you duplicate the color order as shown above. Note how the green pair is not side-by-side as are all the other pairs. This configuration allows for longer wire runs.

Crossover Cables

Crossover The purpose of a Crossover Ethernet cable is to directly connect one computer to another computer (or device) without going through a router, switch or hub.

Preparing Cable

Step 1 Cabling step1 cut into the plastic sheath about 1 inch (2.5 cm) from the end of the cut cable. The crimping tool has a razor blade that will do the trick with practice. Step 2 Ethernet Cabling step2 Unwind and pair the similar colors. Step 3 Ethernet Cabling step2 Pinch the wires between your fingers and straighten them out as shown. The color order is important to get correct. Use scissors to make a straight cut across the 8 wires to shorten them to 1/2 Inch (1.3 cm) from the cut sleeve to the end of the wires. Step 4 Ethernet Cabling step3 Carefully push all 8 colored wires into the connector. Note the position of the blue plastic sleeve. Also note how the wires go all the way to the end. to be continue...
