  • Optical Transmission Network A National Treasure

    Optical Transmission Network A National Treasure

    The Optical Transport Network (OTN) is a high-speed, high-capacity transport technology that has revolutionized modern telecommunications. Key elements of OTN include: Standardized framing (the “digital wrapper”): OTN adds overhead. Functionally standardized interfaces may have reduced tributary slot capacity on one or more of the 100G “slices” – OTUCn-M consists of n full or partial 100G slices and has M total 5G tributary slots of capacity. Aggregate size can scale in steps as small as 5G. OTN is built on a series of protocols, including G. Basic Concepts and Working. Smart grid's digital substation is the focus of State Grid Corporation of China (SGCC) in recent 10 years. From the first 220 kV smart substation built 10 years ago to the current goal of 8000 smart substations, the upgrade of optical fiber communication networks has played an important role in. Open Transport Network (OTN) is a flexible private communication network based on fiber optic technology, manufactured by OTN Systems.
