Review on High-Quality CAT6 Plenum Cable 1000ft (CMP) for Easy Installation, Tested Plenum Rated Wire - 23AWG Solid Conductor, 550MHz, 4Pair 10 GB UTP Internet Cable in Multiple Colors (Blue) by Nick Atkinson

My mistake here as I should have looked closely. this product. This cable is made of Copper Clad Aluminum (CCA). We connected our entire shelter to it and later found that the cable was not working properly. Devices that should connect with 1GB will not connect and these devices will experience intermittent issues and disconnects. Please note that these devices use POE. Simply replacing the CCA cable with a pure copper cable with the same connectors works great. Unfortunately, we now have to rebuild our entire shelter. I want to remind you that this is a plenum cable which makes it quite stiff.
