Ethernet Verifier for Network Connectivity Testing and Troubleshooting

An Ethernet verifier (network verifier tool) checks the basic functionality of data links using practical tests without reference to normative limit values.

It verifies whether a network connection works reliably under real-world conditions—for example, when transmitting 1 Gbit/s over copper cabling or fibre connections.

LinkXpert TP and LinkXpert M3 combine cable testing with active network diagnostics, enabling fast commissioning, troubleshooting, and documentation across copper, fibre optic, and WLAN networks.

A network verifier checks whether a connection is fundamentally functional—without evaluating against formal certification standards.

Using the LinkXpert TP or LinkXpert M3 as an example, once the cabling type is detected, automated tests consisting of several practical checks can be performed:

• Wiring test – verifies correct cabling and detects miswires
• Bit error rate test (BERT) – sends real data packets and verifies error-free transmission
• Signal-to-noise ratio (SNR) – evaluates transmission quality and stability
• PoE load test – loads the line with up to 90 W to validate PoE performance under real conditions  
• Network scan – identifies connected devices, VLANs, IP addresses, and network topology 

All results are clearly displayed on the touchscreen and can be saved for documentation.

This enables a verifier to confirm whether a network operates reliably in real-world conditions—even without formal certification testing.
