The pace of new optical fiber research and development needs to be accelerated
In recent years, my country's leading optical fiber and cable companies have vigorously carried out independent innovation, gradually mastered the optical fiber preform technology, completely got rid of the situation of being controlled by others, and the profitability of the entire industry has also been improved. improved.
Zhao Zisen, an academician of the Chinese Academy of Engineering, said not long ago that my country's large-scale optical fiber and cable manufacturers have basically achieved "self-sufficiency in production". Small manufacturers need to import optical fiber preforms. Currently, 70% of the optical fiber preforms on the market are self-produced. production, only 30% depends on imports.
In August 2015, the Ministry of Commerce finally determined that imported optical fiber preforms originating from Japan and the United States were dumped. The release of the anti-dumping investigation results of imported optical fiber preforms maintained a fair competition environment in the domestic optical fiber preform market.
In the research and development of new optical fiber products, ultra-low loss, large effective area optical fiber is the best choice to support the next generation of high-speed, long-distance, and large-capacity transmission. It can be widely used in marine networks and land long-distance trunk networks, and has become The current focus of research and development in the industry.
In 2015, my country’s operators have made clear demands for new optical fibers such as ultra-low loss.
However, overall, my country’s ultra-low-loss optical fiber industry chain is currently weak and there are few mature commercial products. Optical fiber and cable manufacturers need to speed up the development of ultra-low-loss optical fiber.The pace of research and development of optical fiber and large effective area optical fiber to seize market opportunities.
With the increasing globalization of the optical fiber market, the transoceanic submarine cable business has become the most profitable area in the optical communications market, and has become a passport for domestic manufacturers to enter the international high-end market.
While domestic manufacturers are accelerating the pace of internationalization, they have also exposed my country's shortcomings in the submarine cable business and marine engineering.
At present, my country's optical fiber and cable companies still need to strengthen their submarine cable business.
