If the channel is is in-spec, then the geometry doesn't matter. The 802.3 series doesn't specify the cable geometry. They do specify channel parameters like FEX

If the channel is is in-spec, then the geometry doesn't matter. The 802.3 series doesn't specify the cable geometry. They do specify channel parameters like FEXT, NEXT, IL, and RL across frequency ranges of interest. Maybe the CAT specs are more into the cable construction than the performance; I haven't read any of those.
