I am attempting to set up a server with a total of four single-mode fiber ports - two need to be at least 1Gb and two must be 10Gb. I have found a variety of 10Gb single-mode fiber network adapters (for example the Intel X520-LR1 and the QLogic 3242-LR), but no 1Gb single-mode fiber adapters. Do they exist?
I will only have two PCI-E x8 slots (unless I am forced to get a larger server), so both network adapters would need to have two ports.
