Teransceiver & FPGA

Hi,

The Cyclone 10 GX family devices seems to be a good fit  they can support upto 12.5 Gbps, enough for SFP or SFP+ interface. You may implement an Ethernet protocol, a light weight Seriallite III or even a custom protocol with 8b/10b  or a 64b/66b for your application.

If I were you, decision will consider factors like 

1) Whether I need FPGA in my system for other processing as well or rather it is already present so why not use it!

2) If simple data forwarding is required (no processing), then I would go with a simple retimer or PHY device in the path.
