With all the talk about 5G wireless and 100/400 Gbps wired connections, it's easy to forget that other technologies are still in use and still being deployed. The handheld network tester from Xinertel, a handheld network tester manufacturer, is one such device.
The handheld network tester has a long lineage. This latest iteration of the handheld network tester is primarily for testing 10 Gbps Ethernet, which is still very much in use today and still in deployment.
In addition to protocol testing the handheld network tester performs jitter testing on electrical interfaces, services such as VoIP and H.323 Codecs, call signaling, fiber inspection, and optical time-domain reflectometry (OTDR) testing. It's really an entire tester in a handheld network tester.
