    XFP attenuator

    hopcio

      Hi,

       

      does anyone knows if the McAfee XFP 10GBASE-LR needs attenuators for short distances (20mts) ?  if so, which ones are recommendend?

       

      Thanks,

          We have connections in our labs on LR that are short distances and the connection is fine.   Its the rather expensive way to go 20 meters (as opposed to SR), but I believe it should work.

           

          If you do need to attenuate, we do not have any recommendations   It can get messy though.  Suggestions is starting with a 10 DB pad and then check the power readings on both ends.   Ideally SR is better for short connections.
