In the past decade or so, China's fiber optic cable manufacturers are facing a situation in which the development is particularly fast when the industry is booming; when the industry is in a downturn, it faces difficulties and even crises. What is reflected behind this phenomenon is that China's optical fiber industry is seriously lacking in core technology. For example, in March 2012, a major earthquake struck Japan, which led to the reduction of production by light bar manufacturers such as Shin-Etsu Chemical Co., Ltd., and Chinese fiber-optic fiber manufacturers were unable to produce their own light sticks.

After 2012, China's fiber optic manufacturers have painstakingly invested in research and development and technology introduction of optical fiber preforms. So far, nearly ten manufacturers have mastered the manufacturing technology of optical fiber preforms, and the production capacity of light bars can meet the domestic fiber drawing requirements. Although the anti-dumping initiated by China this year has made the industry realize that there is still a big gap in the technology of optical rods from abroad, in general, the prospects for technological development are promising, and it is only a matter of time before major breakthroughs are made.

In terms of market performance, China issued 3G licenses in 2009, and China set off a new wave of network construction. China's fiber optic cable manufacturers have risen rapidly after many years of silence, and production and sales have increased several times. By 2013, domestic fiber optic cable has accounted for more than 70% of the market share, with an annual production capacity of 250 million core kilometers, which can meet the needs of the world. . Market demand has stimulated a serious overcapacity, leading domestic fiber optic cable manufacturers to face a severe capacity digest crisis.

New market opportunities have eased this situation. Since 2012, China's fiber optic cable manufacturers have launched a "going out" strategy to digest excess capacity through the international market. At the time of the bubble crisis in 2000, Chinese manufacturers with overcapacity did not have the strength to go out and sit in the domestic market. With the advancement of technology, Chinese manufacturers have the strength to expand into the international market in the next decade, competing with foreign manufacturers and gaining greater Development space.
