Ethernet Testers

Ethernet testers are devices used to verify, measure, and troubleshoot Ethernet networks. 

Ethernet networks often fail due to invisible physical-layer or link-layer issues, even when devices appear connected. Ethernet testers help engineers quickly find the real cause of problems such as:

  • Slow or unstable network speeds
  • Intermittent packet loss or link drops
  • Failed 1G / 2.5G / 10G link negotiation
  • Cabling faults hidden behind walls or racks
  • Poor network quality after installation or upgrades

TFN offers high-quality Ethernet testers for gigabit and 10 gigabit networks.
