We're about to get a new 100 mb internet circuit run to our office via existing fiber (currently at 5mb). The CPE from the carrier has SFP ports available so I had them leave a multi-mode LC fiber SFP for us for a 'future' change from copper to fiber on the very short run from their switch to ours (in the same rack).
Are there any advantages to fiber over copper on a link of this speed and short distance? Reliability/latency/traffic handling/etc.? Any insight would be greatly appreciated.
Copper will likely be more reliable over such a short distance as fiber relies on optical transceivers and the laser diodes do fail. And worse yet they often get flaky before completely failing.
