Hi everyone. I need a 15m ethernet cable to run through the floor between a desktop and a switch. Ideally already terminated as there's space to get the plugs in. I've never bought anything more than an Amazon special but as this is going semi permanently under the floor I want a decent one. Am I right to avoid CCA? Do I need cat 6 to be sure of gigabit speeds? Any recommendations for online shops? General pointers? Thanks!
