[http://www.molex.com/molex/family/intro.jsp?superFamOID=-16821&pageTitle=Introduction&channel=Products&familyOID=-12001&chanName=family&frellink=Introduction Molex] creates one such module supported by the FPGA. |
| 84 | The two SFP connectors require an additional module. One common SFP module is a Gigabit Ethernet interface. We have successfully tested two Gigabit Ethernet modules: Molex part 74741-0005 (available from [http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=WM1665-ND Digikey]) and Add-On Computer part GLC-T-AO ([http://addoncomputer.com/products/glc-t-ao.html details]). Other modules which adhere to the SFP specification should work as well. |
