Knowing that a CAT 5e cable should have been enough I did not save in the wrong place and had therefore at this much more expensive cable resorted - simply with the fact that if possible should happen less transmission errors or no. Plugged and installed with 4 other cables in a cable duct on my Fritzbox 7390 but produced this massive cable faults, among other things artifacts and frozen images in approximately 90 second intervals. Whether it is in general the cable or the flat design I can not judge, a 10 m long double round CAD 5 cable was additionally collected works fine
