How Do You Make Ethernet Loopback Cable?
An Ethernet loopback cable is a portion of Ethernet cable where wires loop back around to the same plug that they originated from. This can be very useful when testing computer networking equipment, because it does not require a network to actually be in place for the tests to occur. Because the cable loops back on itself, information that is sent through the cable will return as though it was being sent from another computer. Creating an Ethernet loopback cable is relatively easy, requiring only a few minutes and basic Ethernet cable tools. Measure a 6-inch portion of an Ethernet cable and cut both ends of it off. Carefully slice the cable’s insulation down the length of the portion you have created, exposing the wires inside. Remove a single braided pair of wires from the insulation. Unbraid the wires to a length of approximately 2 inches on each end, then use your wire stripper to strip half an inch of the insulation from each end of the two wires. Line the wires up with the uncrimp
