ITU-T G.709

ITU-T G.709 is a global standard that defines how high-speed digital communication networks, like optical fiber systems, transmit large amounts of data efficiently and reliably. It specifies frameworks for encoding data, managing different data rates, and ensuring synchronization across complex networks. Essentially, G.709 helps different equipment and systems communicate seamlessly, enabling the backbone of internet, telecommunication, and data services to operate smoothly at very high speeds while maintaining data integrity over long distances.
