Typical arrangement for supporting cables in mid-span is to use a
"messenger wire."
This is a steel, or some non-stretchable wire, and is run from one point to
another,
with some form of "tie-off" every 2 feet or so to support the cables under it.

If you notice telephone wires (from the pole to the house) have a
"built-in" messenger
wire moulded into the overall cable sheath and is noticeable if you look
closely.
