When connecting switches back to central location is there any reason to use fiber optic over cat 6? This is of course assuming that the distance is less than 100 meters since cat 6 loses 1 gigabit speed transfer after that.
FYI: That's Gb, not GB. And yeah, I max out gigabit ethernet easily. Can't imagine it in a corporate network.
My guess is that copper won't go over 10G without serious shielding or link aggregation, yet we see 100G over fibre in places where they're seriously bandwidth-starved (e.g. undersea cables), and that will filter down, and still has room to grow.
