Have ordered around my living room to the first floor via ductwork to connect this cable. I was of course forced a plug so I abzuzwicken through the pipes come. After about an hour the worst was done. The cable was on the first floor. When I removed the shield but I got a little shock. No coding as orange / white, green / white, or the same but only very orange, very green and 4 white veins. If you plan something and will then crimping the cable itself should bring some experience when it comes to network. But for that the cable is not well thought basically.
All in all I can say. Very good cable to reach transfer speeds and on my home server of 80-85 MB / s. I'll go even assuming the cable could even more just pushes my hardware to its limits.
