Review on UGREEN Coupler Ethernet Extender Adapter Computer Accessories & Peripherals and Cables & Interconnects by Edward Henderson

These suck. It is not known if these connectors are unidirectional in network data cables. There are no instructions on the packaging. I have only used this product for two patch cord extensions where I had to rotate the connector to ensure data signal continuity. I wouldn't recommend a POE cable either. I tried to use this product with a POE camera cable and the POE/DVR module failed. All other camera signals disappeared and the feed stopped. I had to unplug this adapter and rebuild the dash cam to reconnect to the network afterwards, which gave me a sense of relief because it looked like the thing was on fire. It only took me an extra 10 feet to complete the barrel, but this connector doesn't work for POE applications. Do not use it to route POE cables.
