The north face is a documented alpine route on Pic d'Olan and is generally considered more serious than the normal route. It involves steep mixed climbing on a large mountain face, with objective hazards from rockfall and changing snow conditions. Route-finding can be complex, especially in poor visibility or when the face is not in good condition. The climb is sustained and more committing than a standard ridge ascent. It is appropriate only for experienced alpinists comfortable on steep alpine terrain. Exact timings and metrics are not consistently documented in the sources I can verify.
