Do the wave modes offer higher velocity?

  Yes, basically most of the electromagnetic wave is in the hollow (gas-filled) core, which is going to have an index closer to 1 (as opposed to ~1.4 for silica fibers.)

    Oh, wow! Thanks for clarifying. I get it now! (Former optical engineer, but not in fiber optics.)
