Very High speed serial communication using the STRATIX II GX FPGA

Check out SerialLite II also. It is a very thin layer on top of the transceivers and very easy to use. You can also turn on fancy stuff like CRCs. It supports both one-to-one and broadcast messaging. The IP is free with a full license of Quartus. I have used the transceivers through the HSMC connector, but have no experience with the SFP.

Thank you very much for your reply....

I will try SerialLite II also.

Means you have used the Transceivers TXP TXN RXP RXN pins through the HSMC connectors I think I am right....
