Optical Fiber Supports the Development Of Internet lives

The construction of network infrastructure such as optical fiber and cable and the development of new information and communication technologies have strongly supported the development of various communication businesses and brought great changes to people's lives and production. Since 2015, China has successively canceled the domestic long-distance roaming charges for mobile phones and the "roaming" charges for traffic. The average rate per unit bandwidth of fixed broadband and per unit traffic of mobile networks has decreased by more than 95%, and the average rate per unit bandwidth of enterprise broadband and leased lines has decreased by more than 70%. The annual average benefit of various cost reduction measures has exceeded 1 billion users, and the cumulative profit has exceeded 700 billion yuan. In 2021, the average download rate of fixed broadband will be 62.6Mbit/s, 16.7 times higher than that in 2013; The average download rate of mobile broadband is 59.3Mbit/s, an increase of 4.0 times over 2016. The construction of an optical fiber network has brought about a significant increase in network speed, which has played a supporting role in improving people's quality of life, reducing costs, and increasing the efficiency of enterprises. With the improvement of the service capacity of the information transmission industry and the vigorous development of the new Internet economy, China has made steady progress on the road to becoming a network power.

After ten years of development, the optical fiber and cable industry has strengthened its research and development in such fields as optical fiber preform technology, ultra-low attenuation G.654. E optical fiber, multi-core optical fiber, fiber to room (FTTR) solutions, terminal gigabit optical interconnection products, and special optical fiber cables, taking independent innovation as the core competitiveness, and is transforming from a large optical fiber and cable production country to a powerful country. According to incomplete statistics of the patent database of the State Intellectual Property Office, there are nearly 50000 patents related to optical fiber and cable, ranking the top in the world. At present, improved chemical vapor deposition (MCVD), plasma chemical vapor deposition (PCVD), axial vapor deposition (VAD) and out of rod chemical vapor deposition (OVD) are widely used in mandrel manufacturing. PCVD, VAD and OVD are the main processes in China, and domestic leading enterprises have their own core advantages in light rod technology.
