Two birds, one stone.  With SFP+ ports, one product can be used for either ethernet or fibre 10G connections.  You also don't need to spend the $40 or so on internal components per port to provide those 10GBE ports natively and you keep the entry price point for some pretty capable boxes down while future proofing them.  I certainly don't want to spend another $100 on a switch for 2x10GbE ports I'm not going to use (i just bought an SG-2210P because it supports POE across all 8 ports, to replace a previous 2008P which only does 4) for $150.  Case in point, 16port non-POE 10G switch T1700X-16TS is C$1100 and the 16port POE+ 150W TL-SG1016PE is C$188.

I'm with the TPlink product guy on this one :)  You can 'upgrade' an SFP+ capable Omada router (7206, 8411) or switch (SG2210(M)P etc.) for C$75/port or so and make it 10G capable.

Price per copper port is a bit bonkers...but no SFP's!  Hopefully the shape of the future :)
