I'm using it for connection of my Steinberg MR CSX - professional audio interface in Music Studio. The lenght of this cable (Lindy) is not typical for FireWire standard - Which is about 4.5 meters - this is far above (7.5 meters). Now with Lindy 30864 everything works perfect - Earlier I got problems (audio pops) with even shorter than 4.5 meter cables. Very good professional product !!
