Is the only difference between this
Newegg.com - Intel E10G42BFSR X520-SR2 Ethernet Server Adapter 10Gbps PCI Express 2.0 x8 2 x LC
Newegg.com - Intel E10G42BTDA Server Adapter X520-DA2 10Gbps PCI Express 2.0 x8 2 x SFP+
that one comes with the modules and the other doesn't?
If I order the modules (Newegg.com - Intel E10GSFPSR Ethernet SFP+ SR Optics) separately will they work with both?
