I'm confused.... SFP is not SFP+. SFP carries at most 4.25 Gb/sec. SFP+ works at >10 Gb/sec. So, it's not clear that the MikroTik is very useful in a 10 Gig world. It's not immediately clear but VERY likely, that this is an "edge switch" that is intended for collapsing the GigE copper traffic onto a potentially bottlenecked GigE "local backbone". Of course if you want to go from GigE fiber to GigE copper, that board might be useful.
