Yeah, besides the Xilinx FGPA in the module, the PCB interconnect would have to be specifically the Vitesse Crosspoint VSC3144XHR-12 https://www.vitesse.com/products/product/VSC3144

and you can see from the product brief (https://www.vitesse.com/products/download.php?fid=4548&numbe...) many people use it in telco oriented gear for back-planes and the like.

Here is my take on why you shouldn't buy an ExaNIC from Exablaze (http://meanderful.blogspot.com/2014/11/dont-buy-exanic-from-...)

Just remember that I'm very biased...
