Hi, would you be able to check out the link below for the Dell part you need? ( And we are afraid we are not able to cross check the compatibility with other companies' products.) [URL]   Wish you a Happy Monday & have a great week ahead. Thank you for choosing Dell. 
Hi, After a days of googling I decide to try to get answers from Dell experts. So, I need some help to choose DACs to connect different devices (Next there are just cases): 1) Connect a Dell Poweredge R820 with a QLogic 57840S adapter (Quad port SFP+)  to a Cisco 3560X 2) Connect a Dell Poweredge T430 with an Intel X520-DA2 adapter to a Cisco 3560X 3) Connect the R820 to the T430 I want to ask also witch SFP 10G SR MM transceiver should I chose to connect Dell servers to an optical fiber (Cisco ones can work without issues, or should I take Dell ones, or a transceiver for each brand)? Thank you a lot  
DAC Dell to Cisco
