LB-200 (10/100 Base-T)

Loopback device - Ethernet End-to-end RJ45 x 2

LB-200 is a smart companion of NuDOG. There are two application modes that make on-site network test easy and efficient. One is loopback test and another is asymmetric network transmission test. Common evaluation methodology such as Throughput and Latency test are applied for the test by attached software, NuDOG-2544 and NuDOG device.


  • Features
  • As a loopback client that returns incoming test streams for loopback (round trip) test
  • As a packet generator for bi-directional symmetric/asymmetric (end to end) network test
  • Distinctive LED indicators are able to pinpoint the status of current running network.
  • Handheld device with external and replaceable battery pack that is convenient for on-site network test.
  • 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.
  • Software utility NuDOG-2544 of NuDOG can remote control the test for both NuDOG and remote LB-200
  • Support Round Trip (loopback) and End-to-End (bi-directional symmetric/asymmetric) test mode when LB-200 works with NuDOG
  • Test loopback, throughput and latency function by single network route to remote site.
  • Applications
  • Bandwidth test and verification for connection between different locations of office or building
  • Network bandwidth assurance and verification for ADSL or leased line
  • Solution of Last-mile test between CO (central office) and CPE (customer premises equipment).
  • Throughput and Latency test of point to point wireless transmission for public service
