About The Test Of The Network Cable

You can use the network cable tester to test after the two ends of the crystal head are completed. If the eight indicator lights on the tester are all flashing green in turn, it proves that the network cable is made successfully. If any of the lights is red or yellow, it proves that there is an open circuit or poor contact. At this time, it is best to first press the crystal plugs at both ends and then use the network cable clamp to test again. If the fault persists, check the two ends again. Whether the arrangement order of the core wires is the same, if it is not the same, cut off one end and re-make the crystal head according to the arrangement order of the core wires at the other end. If the core wire sequence is the same, but the tester still displays a red or yellow light after retesting, it means that there must be a bad contact of the corresponding core wire. At this time, there is no way. I have to cut off one end and redo a crystal head in the order of the core of the other end, and then test. If the fault disappears, you do not need to redo the other end crystal head, otherwise you have to replace the original other end crystal head. Cut it out and redo it. Until all the testing indicator lights are green .
