Yeah I think so. There might also be better converter modules. Anyway, my setup is caused by an oversight of not burying light pipes into the floor. Otherwise I guess I'll go with SFP+ too. I'm using TP-Link TL-ST1005 which is the cheapest 10GbE switch out there and it cost like $150. Also RJ-45 adapters/switches run anecdotally hotter than SFP+ ones.
