I really could use (today) something that had more than just two SFP+ ports.
A Mikrotik four port (or more) SFP+ would at least allow 10 gig fiber uplinks -and-downlinks (or a redundant 10 gig fiber link) and be able to connect up some 10 Gig Ethernet-or-Fiber to some local 10 gig servers or other 10 gig switches/routers.
