Teransceiver & FPGA

Hello,

We would like to transmit digital logic signals between multiple FPGA boards over optical fiber.

Is it possible to use the FPGA transceivers with SFP or SFP+ modules for this type of application?

In addition, would it be feasible to transmit these signals across multiple FPGA boards in a daisy-chain configuration, where each FPGA receives the data and then forwards it to the next FPGA through its transceivers?

If so:

Which FPGA families or devices would you recommend for this type of architecture?

Which communication protocol would you recommend?

Is it possible to implement our own custom protocol, or would you advise using a standard protocol instead?

Thank you in advance for your feedback.

Best regards,
