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: 

http://www.altera.com/technology/high_speed/protocols/interlaken/pro-interlaken.html (http://www.altera.com/technology/high_speed/protocols/interlaken/pro-interlaken.html

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.
