FMC vs interlaken

You can't really compare FMC and Interlaken. There isn't anything the same about them - except, perhaps, they're both aimed at supporting higher bit rates.

FMC is Altera's name for a type of physical connector that they (and others) use. Interlaken is a protocol that you might run over a physical link that may (or may not) run over an FMC connector.

Have a read of:

to give you an overview of Interlaken.

Altera's FMC is a custom connector made by Samtec, part number: ASP-134486-01

This connector is used on a number of Altera's development boards.

ok thx..

so if i truelly understood the concept, we can have an fpga board hwo has fmc connector and it implement interlaken protocol

The following Samtec document discussed the high speed characteristics of a cable assembly that mates with the same connector.

It discusses the cable's speed rating and suggests 15Gbps should be possible.

So, yes. You should be able to implement a physical layer link, operating an Interlaken protocol, over the FMC connector.
