Communication transmission network, as the basic network of Smart Central Yunnan Water Diversion Project, plays a fundamental role in intelligent engineering project management. In view of the limitations of common communication system configuration, the OTN (Optical Transport Network) technology based on OSU (Optical Service Unit) is proposed to build the communication transmission network of Smart Central Yunnan Water Diversion Project as a case study. The OTN technology based on OSU is comprehensively and systematically deployed and studied from eight aspects: three network integration, interface type, site, networking mode, service bearing, network protection, docking scheme and intelligent management. The OSU-based OTN technology could effectively solve the complex services of carrying small particle and the high delay caused by excessive mapping levels in traditional transmission network. It also provides a feasible strategy for constructing a safe, practical, intelligent and efficient communication transmission network in the Smart Central Yunnan Water Diversion Project. The research findings are of guiding significance for the practical work of constructing a high-speed, flexible, intelligent, safe and future-oriented transmission network of the Smart Central Yunnan Water Diversion Project, and can also be used for reference for the construction of communication networks in other water diversion projects.
