Optical Line Monitoring
Optical Line Monitoring (OLM) is an essential technology that provides continuous, real-time surveillance of fiber optic networks to ensure optimal performance and reliability. By detecting signal degradations, faults, and intrusions along live fiber links, OLM minimizes downtime and supports proactive maintenance. Fiber Optical Test delivers state-of-the-art OLM systems designed to meet the rigorous demands of modern telecom and enterprise networks. Headquartered in Grand Chute, WI, we are recognized across North America for pioneering innovations, dependable products, and exceptional customer service. Our solutions are developed through comprehensive research and quality control, empowering businesses to safeguard their fiber infrastructure while optimizing operational efficiency.
