What's special about this portable Ethernet tester?

  • Loopback tester works in conjunction with an LED hub or switch, completing the circuit to test shorts, breaks, or incorrect wiring
  • Connects to wall jacks or the ends of network cable that are currently connected to your network, and then sends a signal back to your hub/switch, which will light up if your wiring is good
  • Use this tester for matching wall plate ports to their respective ports in the server room patch panel; simply plug into a wall plate, and watch for the corresponding LED to light up on the patch panel

Many times, when wiring a new building or upgrading to a faster network, network engineers end up wiring a large number of jacks and patch panels to the network. When that's done, they need a way to quickly test to make sure the wiring has been done correctly, and that the new ports are successfully relaying information to the network. The SuperLooper is a small, easy test that does just that. Simply plug it into your newly-wired device, and look for you network hub/patch panel/switch to light up, showing that it's been installed correctly.

Questions & Answers


I have a router/switch with leds showing active circuits. I have multiple cables which terminate in RJ45 wall face plates. Do I just plug the superlooper in a wall faceplate and see if the connected switch LED lights up? My connections are working, but with CAT-6 cabling I expect higher throughput, Is there a way to check this? Can I connect a disk through the superlooper? Does the superlooper just check the two active pairs in the 8 wire cable?
