Gold-plated connectors, however, are only a little show. This is about light waves and that it does not matter what material is used here. The rest of the cable also makes a solid impression. Have unfortunately no way to measure any bit error in transmission here.
Of course you can also buy cable of Oehlbach, however, these costs many times over. This would be quite acceptable at a RCA cable and a high-quality system. Here, however, only data is transferred.
The Telekom laid determined no fiber optic cable around Germany by the company Oehlbach :-))) and faster VDSL works here, too many kilometers. And this cable, however, is so extremely short. Therefore, everything in the green area ;-)
