I am wondering if it is possible to connect a LR optic to one port of the x520-SR2 card or if it only supports SR optics. The chip should be the same for all X520 models or am I missing something?
Otherwise I guess I have to go along with one X520-LR1 and one X520-SR1 which is more expensive.
Also, I am wondering if the X520 cards support 1Gbps aswell since I wont be able to upgrade both ends simultaneously. It should be backward compatible but I know that some SFP+ Modules for example support 10Gb only.
I hope you can help me or maybe lead to the right direction.
Thank you for writing in Wired Communities. I will further check if X520-SR2 can support LR fiber optic. For the gigabit speed, X520-SR2 can support 1 Gbps data rates if using the fiber optical module. Please refer to page 4 of the product brief

You can use LR optical module on X520-SR2. Please refer to additional reference information at https://www.intel.com/content/www/us/en/support/articles/000005528/network-and-i-o/ethernet-products...
-Can I mix different SFP module types and cables on a dual port adapter from the Intel® Ethernet Converged Network Adapter X520 Series?
Yes. You can install any mix of supported SFP+ optical modules, SFP modules, or direct attach cables on the same dual port adapter. You can plug any supported module into any port.
Hi Luigima. I had the same question and foung it, Could you please let me know if actually you tested it. Which means did you put your x520-SR2 card to work with both sfps modules (SR and LR) did it work?
