1. A method comprising:
monitoring real-time electrical data at Power Sourcing Equipment (PSE) transmitting power over a cable to a Powered Device (PD), wherein the power comprises pulse power;
monitoring cross-talk between wires within the cable and an adjacent cable;
identifying cable adjacency between the cable and the adjacent cable based on monitoring the cross-talk;
performing thermal modeling on the cable;
calculating a thermal rise on the cable based at least in part on the cable adjacency; and
performing one or more actions to reduce a risk of unsafe operation at the cable when the thermal rise on the cable is above a threshold level.
