TOOLTOP ET636 4-in-1 Network Cable Tester and Multimeter Features
This 4-in-1 multimeter and network cable tester delivers the 60000-count resolution needed for diagnosing power supply anomalies in network switches and PoE injectors, where millivolt differences signal failing capacitors or thermal drift. The integrated optical power meter measures fiber insertion loss across standard single-mode and multi-mode wavelengths, letting network technicians verify cable plant performance before declaring circuits operational. Its visual fault locator projects a red beam along cable routes to pinpoint breaks or sharp bends that attenuate signal quality in both copper and fiber links. The 4-in-1 design eliminates separate trips to the service van for different measurement tools, reducing diagnostic time from hours to minutes on complex installations. Cable mapping function verifies RJ45 wiring sequence according to EIA/TIA standards, catching cross-pairs and reversed segments that would cause intermittent data loss.

The device is not working properly, some poe does not want to be detected, the store said that it needs to be detected longer, i waited two minutes and it still did not measure poe.
Aliexpress rejected my request, you need to think about whether to buy the device, because it does not work 100%
