10G SFP+ Transceiver compatibility

Hi,

i have the following NIC card “X520-DA2 Dell Low Profile (NIC DELL 10GB 2- PORTS 10GBASE-X PCI-Ex8 SFP+ X520-DA2 LP)” and i'm looking for a compatible 10G SFP+ Transceiver. It looks like this adapter in order to be functional requires specific Transceiver due to igbt driver validation checks. Does anybody know and suggest any compatible Transceiver ?

thanks in advance
