my country has the world's largest optical communications market, but it can only create some enterprises that compete in the low-end market; it has the most complete optical communications industry chain, but the core optical components still rely on imports. A big country in optical communications is not a strong country in optical communications, so it has to be worrying.
　　"Xiongzhou Wuli, handsome stars, Taiwanese gods sleep in the friendship between Yi and Xia, the guest and host enjoy the beauty of the southeast." The passage in "The Preface of the Tengwang Pavilion" is used to describe the optical communication enterprises during the communication exhibition. Every time. Thanks to the great development of China's telecommunications industry, most optical communications companies have already gained considerable scale and have great influence both domestically and internationally. Coincidentally, the telecommunications exhibition is also in September, and at the same time as Wang Bo's preface, these optical telecommunications companies are basically from Jiangsu, Zhejiang and Shenzhen.
　　Staged the grand occasion
　　This telecommunications exhibition, the representative enterprises of China's fiber optic cable and cable manufacturing are Fiberhome Technology, Hengtong Group, Junzhi Group, and Zhongli Group. These companies have accumulated years of experience in the communications industry. The products they exhibit have covered the entire communications industry’s demand for cables: from telecommunications to radio and television, to aerospace, oceans, energy, etc., wherever cables are needed. Complete coverage.
　　It is worth mentioning that Hengtong Group exhibited its optical fiber preforms with completely independent intellectual property rights this time. The optical fiber preforms were engraved with the Chinese mark, which can be described as a model of national enterprise technology research and development. The fly in the ointment is that the current production capacity can only be self-sufficient. The situation that my country still has 60% of optical fiber preforms imported has not yet brought a direct change, but I believe it is only a matter of time.
　　In addition, all optical fiber and cable companies at this telecommunications exhibition demonstrated their ODN overall solutions without exception. At the beginning of this year, China Telecom announced the "Optical Network City" strategy, and China Unicom also launched the FTTH project. One stone has caused a thousand waves of waves. All companies in the industry are rapidly transforming. Those that can produce ODN passive devices are expanding; those that cannot produce have participated through mergers and acquisitions and plant construction. Domestic companies found that the market's response was amazing.
　　However, such a rapid expansion of production also fully illustrates a problem: my country's ODN market has too low a threshold, the products produced do not have much technical content, and the market is easily saturated. Most manufacturers can only rely on frequent price wars to ensure market share.
　　my country has the world's largest optical communications market, but it can only create some companies competing in the low-end market; my country has the most complete optical communications industry chain, but the core optical components still rely on imports. A big country in optical communications is not a strong country in optical communications, so it has to be worrying.
Composing melancholy
　　Every time I read the preface to the Pavilion of King Teng, I am amazed by Wang Bo's literary talents, and I can always experience the helplessness expressed in the text. After looking at the grand occasion of optical communications, it is not difficult to analyze the hidden worries of domestic national enterprises: if there is no such a huge market in our country, what will be left of these enterprises?
　　There is also a foreign company in the optical fiber and cable company-Corning, knows Anyone who knows optical fiber does not know Corning, but how many people who know optical fiber have noticed the gap between domestic companies and Corning? In this exhibition, Corning's booth scale, exhibitors, and product types are somewhat inconsistent with the background of multinational companies. However, every exhibition of Corning has made people amazed by its more than 40 years of experience accumulation in the field of optical fiber and its absolute leading technological innovation capabilities.
　　The optical fiber used for ultra-long-distance high-speed transmission with a loss of less than 0.18dB/km; the optical fiber that traverses the Qinghai-Tibet Plateau with an average altitude of more than 5000 meters, works in a low temperature environment below minus 20°C to ensure the communication project of the State Grid. This is Corning's performance in leading the world in technology. In detail, how many companies would care about the short jumper on the data center cabinet? And it is based on this jumper that Corning's "E-Jun" program can bring in $1 billion in revenue every year.
　　An engineer from a domestic manufacturer once said: “Every time we purchase some devices, we always hope to use as many domestic products as possible, but many times we give up during technical evaluation: the same device, domestically produced products. The specifications and colors are not all the same, how do we use it?”
　　As Mao Qian of Wuhan Academy of Posts and Telecommunications said: “The power of communications cannot be built solely by introduction. At the same time of introduction, there must be digestion, absorption and innovation. , Improve and develop its own national communications industry to support the establishment of a communications power."
