Ethernet Qualifier for Network Performance Testing up to 10G

An Ethernet qualifier (network performance tester) checks whether an existing network infrastructure reliably delivers the performance required for current and future applications.

It evaluates not only the cabling, but the entire transmission path, including active components such as switches and endpoints.

This ensures that stable data rates from 1 Gbit/s up to 10 Gbit/s are achieved under real-world conditions.

The NetXpert XG2 from Softing IT Networks is a powerful Ethernet performance tester designed for installers, IT service providers, and network operators who need to verify network performance quickly and reliably.

An Ethernet network qualifier performs practical measurements across the entire connection—from the network outlet to the active device.

Using the NetXpert XG2 as an example, the test sequence includes:

1. Automatic line diagnosis – checks wiring, cable length, and wire pairs to detect installation issues
2. Bit error rate test (BERT) – sends real Ethernet packets at selected speeds (1–10 Gbit/s) and verifies transmission integrity
3. Signal-to-noise ratio (SNR) – evaluates transmission quality and ensures stable operation
4. PoE load test – verifies reliable power delivery up to 90 W for devices such as access points, cameras, and IP phones
5. Network detection and ping tests – identifies switches, VLANs, IP addresses, and verifies network reachability 

All results are clearly displayed and can be saved and exported for acceptance testing and project documentation.

This enables reliable verification that the network infrastructure meets performance requirements for modern applications.
