Coherent optical fiber communication system with 336 Tb/s transmission uses single light source

An international research team led by the Photonic Network Laboratory of the National Institute of Information and Communications Technology demonstrated a coherent optical fiber communication system with a total transmission capacity of 336 Tb/s. The system uses a single light source combined with optical comb generation and frequency reference distribution, eliminating the need for hundreds of built-in light sources within transponder modules.
