Cat 6A maybe the solution to your PoE+ cable power loss problem in lighting, IP cameras, wireless access points (Bluetooth or RFID) applications.
According to a recent report by Pacific Northwest National Laboratory for the U.S. Dept. of Energy November 2017 and revised in July 2018. Cat 6A cables offers less cable power loss than Cat 5E or Cat 6 in LED lighting applications. This is due primarily to the larger diameter of the 23awg copper conductor used in Cat 6A.
