WDM/its OTN and PTN, the use of new technology, new equipment such as SDH, greatly enhanced the western China's ability to cope with a provincial backbone network IP is changed larger particles business, of which 2.5 G or more particle bearing, circuit principle, using WDM/otns priority particles under 2.5 G circuit should adhere to PTN supplemented, SDH bearing, reduces the network construction cost, greatly improve the convenience and flexibility of business configuration, so as to improve the operational efficiency, reduce the operational cost. This project provides a good technical support for the rapid growth of China Mobile's interprovincial high-speed transmission channels and data service traffic, improves the bandwidth utilization of IP service, and creates gratified social and economic benefits.

☆  Technical Highlights of Project Implementation: The regional geological conditions involved in this project are complex and changeable. Most of the stations travel between the mountains and the Qinghai-Tibet Special Line. The highest altitude of the stations along the way is nearly 5000 meters. After winning the bid in June 2013, our company actively organized technical forces to study the project plan and carry out the preparation work. In order to ensure the smooth implementation of the project, the company specially established the Mobile trunk engineering headquarters, which was fully responsible for the real-time communication and coordination with the headquarters of China Mobile Group and the allocation of resources in various provinces, as well as the reasonable allocation of professional and technical personnel, vehicle instruments, etc., and selected the OTN/PTN core technical backbone of the company to form the project research team; The backbone network of this project adopts OTN and PTN equipment from the leading manufacturers of Huawei, ZTE and Fiberhome, and the company's project technical team will work with the manufacturers to overcome difficulties. Through careful organization and planning, the project was successfully completed and accepted in May 2014, lasting 10 months. This project won the National Quality Engineering Award in 2016.
