SFP+ Cable Distances defined by Core Size and Band Width

Did you know a standard SFP+ SR supports a link length of only 26m on standard Fiber Distributed Data Interface (FDDI)-grade multimode fiber (MMF). Using 2000MHz*km MMF (OM3), links up to 300m link lengths are possible. Using 4700MHz*km MMF (OM4), up to 400m link lengths are actually possible.
