A Cat6 patch cables of about 45 m had to get on both ends RJ45 connector (from the router to the switch). 2 Crimpversuche brought no useful results (is more difficult than on the nice internet instructions shown). The Telegärtner plug is on the other hand 1a described with German instructions, totally easy to assemble and makes a high quality impression. It worked anyway everything right away. The price is relatively high - but it's worth the money!
