Perform root cause analysis and lead corrective actions for quality issues, with focus on common cable failure modes such as insulation cracking, conductor fatigue and breakage, poor crimp termination, increased contact resistance, PoE-related overheating in bundles, shield discontinuities, and strain relief failures. Develop and execute robust qualification plans tailored to cable commodities, including temperature rise testing under PoE load, bundle heating validation, flex-life cycling, insulation resistance, hi-pot testing, and electromagnetic interference and electromagnetic compatibility (EMI/EMC) compliance.
