I'm going through old switches laying around and find myself troubled by all the different connection types the PCI adapters and their SFP have.
I found a 10GE (gigabit ethernet?) SFP that says it's a Fiber channel (Brocade 57-0000075-01) and then I get one that says Fiber Optic (Intel TXN310110000000) or even yet, a Cisco adapter that says optic but means both (CC2-N320E-SR (B) 110-1088-30 B0) but I cannot seem to figure out (easily) which one is which even by searching their model numbers (I have many, many more laying around, these are exemples)
Wherever I go, if I ask what is the difference between Fiber Channel and Optic says it's the same but if I ask what is Gibabit Ethernet says it's both copper or Fiber optic. I'm getting frustrated, I just want to not put a FC gizmo with the GE ones and vice-versa...
