How is TLK3134 configured for 10G Ethernet application?

We want to use TLK3414 to implement 10Ge between FPGA and Computer.

But as its output is XAUI, so if we use fibre method, then one XAUI->SFI, and one SFP+ module is needed, it's very cost. And I have no idea about which device to choose for XAUI->SFI. BCM8727 maybe is one choice, but no datasheet.

If we use 10GBase-T method, then how to transfer XAUI? Any recommendation?
