  The Akutsu-Deguchi-Ohtsuki (ADO) invariants are the most studied quantum link
invariants coming from a non-semisimple tensor category. We show that, for
fibered links in $S^3$, the degree of the ADO invariant is determined by the
genus and the top coefficient is a root of unity. More precisely, we prove that
the top coefficient is determined by the Hopf invariant of the plane field of
$S^3$ associated to the fiber surface. Our proof is based on the genus bounds
established in our previous work, together with a theorem of Giroux-Goodman
stating that fiber surfaces in the three-sphere can be obtained from a disk by
plumbing/deplumbing Hopf bands.
