CWW watching the Winter Olympics | long-flying wisdom, cheering for the Winter Olympics!

On February 4, the Olympic flame once again lit up the night sky of Beijing, lighting up the world's first "City of Two Olympic Games", and the opening ceremony of the 2022 Winter Olympic Games was held at the National Stadium.

As an important historical node and a major landmark event in the mainland, the Beijing 2022 Winter Olympic and Paralympic Winter Games are not only the top events in the global sports world, but also an important opportunity for the mainland to show its own image, promote all-round development and invigorate the national spirit. Doing a good job in ensuring the infrastructure of the Winter Olympics is not only the unshirkable responsibility of corporate citizens, but also a rare opportunity to show the achievements of scientific and technological innovation in the mainland. As a leading enterprise in the optical communication industry, Changfei Optical Fiber and Cable Co., Ltd. (hereinafter referred to as "Changfei Company") gives full play to its advantages in the field of optical fiber communication and contributes wisdom and strength to the Olympic Event with diversified products and services.

Actively participate in the construction of green electricity

Add color to the Green Winter Olympics

One of the main features of this Winter Olympics is "green environmental protection". As an important measure of "green Olympic Games", the Beijing Winter Olympics mainly rely on the ± 500 kV Zhangbei Renewable Energy Flexible DC Power Grid Experimental Demonstration Project (hereinafter referred to as "Zhangbei Rouzhi Project") to achieve 100% green power supply for all venues for the first time in the history of the Olympic Games with wind power and photovoltaic power generation in Zhangjiakou area.

Completed and put into operation in June 2020, Zhangbei Soft Dc Project is the world's first flexible DC power grid project, and also the flexible DC project with the highest voltage level and the largest transmission capacity in the world, and its core technology and key equipment are international firsts, and 12 world firsts have been created. In the Zhangbei Rouzhi Project, Changfei Company provided self-developed products such as Quanbei Super Ultra-low Loss G.652 Optical Fiber, Flexible Straight Valve Tower, Circuit Breaker, Energy-Consuming Equipment, and Special Optical Fiber Cables and Components used in Wind Power photovoltaics, and provided on-site services for relevant integrated manufacturers and customers, contributing to the "Green Olympics".

Among them, it is worth mentioning that the DF all-shell ultra-high loss G.652 fiber, its ultra-low attenuation performance and excellent bending insensitivity performance, to meet the UHV engineering ultra-long station distance transmission performance indicators, the deployment of the fiber in the Zhangbei soft straight project, for the first application of domestic ultra-low loss fiber in uh-low voltage project, but also broke the monopoly of foreign ultra-low loss fiber in the field of power communication. After the application practice of many projects, it has been proved that after more than 2 years of operation, the optical fiber performance is stable, the service it carries is running reliably, and the application condition is good.

Help the construction of communication networks

Contribute to the Winter Olympics of Wisdom

A stable communication network is an essential element to ensure the smooth progress of the Winter Olympics, the premise of various wonderful smart Winter Olympic applications, and an important channel for a large number of videos, live broadcasts, and news reports to the world. And these information services based on communication technology are inseparable from the important communication infrastructure of optical fiber and cable.

During the preparations for the Winter Olympics, Changfei Company participated in the construction of base station transmission access projects in the Winter Olympic venues and traffic trunk lines in The Zhangjiakou Competition Area of China Unicom, and the construction of new transmission projects such as multiple competition areas, road sections and venues of China Tower, providing it with high-quality optical fiber and cable products, and helping to build a high-quality, high-speed 5G boutique network with stable optical fiber transmission lines, contributing to the "Smart Winter Olympics".

At present, the Beijing Winter Olympics is presenting the event in an unparalleled way, and all of this is inseparable from the blessing of scientific and technological innovation, the application and promotion of digital intelligence technology and products. Changfei Company, which takes innovation as the source, will continue to develop more high-performance products with leading technology with excellent quality and excellent scientific and technological innovation ability in the future, and work with industry partners to move towards the future!
