The total capital expenditure of the three major operators is estimated to be RMB340.6 billion with a spike of 2.28% over the previous year, of which RMB184.7 billion (up 5.12% year on year) will be involved with 5G. In 2021, 5G networks remain the focus of investment.

In 2020, China Tower's capital expenditure swelled by 36.87% year on year to RMB37.122 billion. In 2019, the 5G layout began to advance, so that the capital expenditure of the three major operators and China Tower rebounded.Īmid the accelerated deployment of 5G in 2020, the total capital expenditure of the three major operators jumped by 11.04% year on year to RMB333 billion, of which RMB175.7 billion was spent on 5G with a significant increase of 326.46% over the previous year. From 2016 to 2018, the capital expenditure of three major operators (China Mobile, China Unicom and China Telecom) and China Tower kept declining as the 4G network market became saturated. Optical fiber communication is the only downstream industry of optical fiber preforms. The main patent applicants include YOFC, Futong Group, Hengtong Group, FiberHome Telecommunication Technologies, ZTT, etc. In recent years, Chinese manufacturers have made more efforts in the research and development of technologies for optical fiber preforms, and filed over 250 patent applications each year. In recent years, Ministry of Commerce of China has adjusted anti-dumping duties on major Japanese manufacturers. As for import, Japan is the largest source of optical fiber preforms for China, making up 80% of China’s imports in 2020. In terms of export, India is the largest export destination of Chinese optical fiber preforms, accounting for approximately 72% of China's exports in 2020. In 2020, the average import unit price (US$155.53/ton) doubled the average export unit price (only US$70.83/ton). There is a huge gap between import and export unit prices of optical fiber preforms in China. However, as the capacity of domestic optical fiber preforms continues to increase and the self-sufficiency is strengthened, the import volume of optical fiber preforms in China has declined year after year at the same time, the export of optical fiber preforms in the country has swelled year by year. In the future, with the acceleration of 5G network construction in China and even the world, it is estimated that the output of optical fiber preforms will hit 12,800 tons by 2026.Ĭhina has always relied heavily on imported optical fiber preforms. In 2019, China's optical fiber output reached 289 million fkm, a year-on-year increase of 9.0% meanwhile, the output of optical fiber preforms jumped 8.1% year-on-year to 9,513 tons.

The global construction of 4G and FTTH requires less optical fiber and cable, which has dragged down the demand for optical fiber preforms however, the burgeoning 5G network has triggered more demand for optical fibers and optical fiber preforms. With optical fiber manufacturing facilities across the globe – including multiple locations in the United States, China, India, and Poland – every optical fiber is shipped with the same reliability and performance standards that distinguish Corning products from all others.Optical fiber preforms play a key role in the optical fiber communication industry chain. We design and build our manufacturing equipment for process control and product consistency, and every centimeter of optical fiber produced is proof-tested to ensure it meets the highest strength requirements.

This means that every strand of our fiber has full traceability to every step of our process, all the way back to raw materials.Įvery step of our manufacturing process is put through exacting and diligent quality control, providing unmatched performance characteristics including dispersion, attenuation, fiber geometry, and bandwidth. The root of this success? A steadfast and unique focus on and commitment to the processes and principles that drive manufacturing excellence across the globe.Ĭorning produces all the glass for our optical fiber from raw materials, ensuring the highest quality and performance over the fiber’s entire service life. This eventually resulted in the production of more than 1 billion kilometers of optical fiber, nearly one-third of all terrestrial and oceanic optical communications networks. Soon after inventing the product, and even before a large order had been placed, Corning began developing the processes that would set the standard for manufacturing excellence across the industry. Without a way to manufacture the product, with consistent reliability and performance, the invention would be futile. Corning’s invention of low-loss optical fiber was a milestone that forever changed the communications landscape.
