The maximum vertical rise is the distance over which the cable is vertically self-supporting. This distance is a function of the weight of the cable and the:

The sheath fire rating (plenum vs. riser) describes flame and smoke performance in a fire, which is unrelated to the cable's mechanical load-bearing capability.

The number of fiber strands affects optical capacity and loss budget, not the mechanical tensile strength or self-supporting distance.

Hangers provide intermediate support points along an installed run but are a separate installation variable, not a property of the cable's inherent self-support rating.

Fire stops are passive firestop materials used to seal cable penetrations and have no effect on the cable's ability to support its own weight over a vertical span.

As a cable hangs vertically, its own weight creates downward tensile force on the conductors and sheath. The cable's maximum tensile rating specifies the greatest load it can sustain without stretching, kinking, or breaking internal elements, and this rating directly determines the longest self-supporting vertical run before mechanical support (hangers) must be added.
