Xilinx UltraScale VC108 - How to connect SFP to CFP2/QSFP28

Hello

 

I want to port a design from a Virtex-7 VC707 Evaluation Board to an UltraScale VC108 Evaluation Board. For the VC707 design, we have used an SFP optical module to connect to another FPGA board that also has an SFP optical module. We cannot touch the other FPGA board. Is it possible to have an optical interconnect over SFP between UltraScale VC108 FPGA and the other FPGA board?

 

The UltraScale VC108 board contains a QSFP28 cage and CFP2 cage, which are not used in our design so far. Both FMC connectors are already in use. Is there any adapter that allows me to convert SFP to CFP2/QSFP28?

 

Thanks in advance.

I don't think you'll have any luck with the CFP2, but there should be plenty of QSFP to SFP adapters out there.

 

Googling for "QSFP to SFP" gives, e.g.

direct attach cables and

socket adapters

 

There's probably something there that you could use.
