Fiber Optic WDM Networks are systems that use wavelength division multiplexing to transmit multiple data channels simultaneously through a single optical fiber. NEC Labs America advances WDM research by developing AI-based optimization, improving bandwidth, fault tolerance, and scalability. These networks form the backbone of global communication and support the rapid growth of data and AI workloads.
This paper outlines QoT-driven optimization strategies in coherent fiber-optic WDM networks, addressing distinct transmission scenarios, QoT metrics, control-plane methodologies, and emerging trends to enhance network reliability, flexibility and capacity.
