Loopback test device Ethernet Loopback slave RJ45 x 2

In general, to perform a loopback test requires two test ports on both packet generator and DUT/NUT for transmission and receiving of test packets. It may not be available to do the loopback test in real network environment if the network under test is located far away from the packet generator with only one linked network cable.


  • Features
  • Clear the status LED by hotkey any time for next loopback test. Status is kept unless clear hotkey is pressed.
  • Distinctive LED indicator that is able to pinpoint the status of current running network.
  • Elapsed Time shown on LED digits display in order to know the duration of a single test.
  • Handheld device that is portable to any test site.
  • Perform round-trip Throughput and Latency test by NuDOG with NuDOG-2544 application software.
  • Real-time LED indicator of network speed, duplex mode, loopback / PG mode, packet length, common errors (CRC, Loss), utilization and elapsed test time in LED digit display.
  • Two network ports for 2 sets of individual loopback test simultaneously. Convenient hotkey to switch the loopback mode for different port (A or B) in the test.
  • Two selective Loopback modes. Layer 1 loopback and Layer 2 loopback for two individual port.
  • Applications
  • Detect network link status for troubleshooting / debugging purpose after wiring of network cable.
  • Monitor network utilization by real-time LED indicator
  • Perform network Throughput and Latency test by NuDOG with NuDOG-2544 software application tool.
  • Work with packet generator such as NuGOG of Xtramus for loopback test
