Submarine System is the infrastructure that supports subsea communication, including cables, repeaters, and landing stations. At NEC Labs America, research focuses on enhancing submarine systems with AI and fiber optic sensing to monitor health, detect faults, and extend service life. These advances ensure secure, high-capacity global communication. By applying distributed sensing, NEC transforms submarine systems into intelligent infrastructure supporting resilient worldwide connectivity.
A simple and accurate semi-analytical model for predicting the gain of a single-stage erbium-doped fiber amplifier embedded with an unknown gain flattening filter is proposed for precise system equalization that is crucial for submarine systems.
