Consider that cost to manufacture the cable goes up as you put stuff in it. You
not only need sensor packages, you also need to connect them so they can report
data. Unless the sensors are optically powered and linked, they would
compromise the inherent lighting immunity the fiber provides.
It's a *lot* easier to do the same thing with a round trip traverse of the
entire optical link. This is already done by at least one supplier of these
parts. It may be done by several others as well.
Cable delay is not the limiting issue on most short link systems. It's not
clear that data rates would be improved by delay modeling.
I took the suggestion as providing a way to provide a timing reference
at the cell site (used for a variety of purposes E911, etc.) instead of
GPSDOs and Rb clocks, not so much improving data rates.
