    QDR vs FDR Cables and 56Gb


      This has been on my mind for a while.  I am sure this have been covered somewhere, but I have been reading for the past hour and have not come up with an answer.


      Is there a difference between QDR 40Gb and FDR 56Gb cables?


      I have ConnectX-3 Cards and SMX6036 Switch, but they are syncing up at 40Gbs.  I am using HP Fiber optic cables HP 498386-B24.  The cables are marked as QDR.


      Going forward I wanted to know if I needed to purchase cables specifically marked for FDR, and if so how do I distinguish.  It seems cables are usually marked as QSFP+ or DDR or QDR. Not many mention FDR.

          FDR cable also tagged 56Gb in blue color.

          If you have a SX6036F FDR14 Infiniband switch, you also access User Guide and Release Notes on web management UI.

          These guides also have several informations supported cables that distinguished with part number.
