this is a UTP cable (Unshielded Twisted Pair UTP =), as it is unshielded, it is flexible and lightweight. It is easy to press to follow the contour of the baseboards. It has a small diameter and can pass under a door The cable and the connectors are of good quality: ca trust. I have not yet had the opportunity to test it on a 1Gpbs connection, 100Mbps but it works very well.
