Cable Testers are responsible for inspecting, testing, and certifying various types of cables—such as fiber optic, coaxial, and Ethernet—using specialized equipment. On a typical day, they might perform continuity tests, identify faulty wiring, document test results, and report their findings to supervisors or project managers. Cable Testers frequently collaborate with installation teams, engineers, and quality assurance staff to ensure projects meet safety and performance standards. This role often involves travel to job sites, attention to detailed procedures, and a focus on both preventive and corrective maintenance.
