The Ethernet industry’s third party testing lab

The UNH-IOL has been providing Ethernet testing services since its inception in 1988. We have a strong and wide-reaching industry reputation and participate in many industry organizations including the IEEE, the Ethernet Alliance, and the OpenAlliance. We were honored to receive the IEEE-SA Corporate Member of the year award in 2013 for "unwavering contributions to interoperability testing of IEEE standards".

We offer the most comprehensive Ethernet testing in the industry covering both conformance against standards and interoperability testing for all Ethernet speeds from 10 Mb/s to 100Gb/s. We have over two decades of providing Ethernet verification, which has led us to having one of the largest interoperability test beds of recently released and legacy devices. We also develop custom PHY tools that are unavailable anywhere else providing deeper conformance of the Ethernet stack.
