Wuhan occupies an important strategic position in the field of optical communication in China. East Lake high tech Zone has developed into an important R & D and production base of optical fiber and cable, optical chip, optical device (optical module) and optical communication system equipment in China. The picture shows that the Optical Valley Exhibition Center has attracted many science and technology enterprises and foreign visiting groups to visit here.
Wuhan speeds up the building of "965" industrial cluster, and "optical core screen end network" is highly expected as a pillar industry. As the birthplace of China's optical communication industry, Wuhan's "light" shines farther and brighter.
According to the municipal development and Reform Commission, Wuhan occupies an important strategic position in the field of optical communication in China. The East Lake high tech Zone has developed into an important R & D and production base of optical fiber and cable, optical chip, optical device (optical module) and optical communication system equipment in China. Among them, the international market share of optical fiber and cable exceeds 25%, the sales volume ranks first in the world for many consecutive years, and the international market share of optical devices exceeds 12%.
How does the optical communication industry grow from big to strong? Wuhan has anchored a high level of self-reliance and self-improvement, unswervingly followed the path of independent innovation and made repeated breakthroughs.
■ Market competitiveness
From following to leading, Wuhan enterprises consolidate the global leading position of optical communication
Last month, Changfei optical fiber completed the acquisition of a famous enterprise in South America. At present, Changfei's products and services have covered more than 70 countries and regions around the world, established 4 overseas bases and more than 20 sales companies, and formed an overseas production, marketing and service network radiating the world.
More than 20 years ago, China formulated standards for the world communication industry for the first time, solved the technical problem of transmitting Internet services on traditional telecom networks, and got rid of the role of follower.
Changfei optical fiber is the epitome of China's optical communication industry.
In 2016, the three main businesses of Changfei preform, optical fiber and optical cable won the first place in the world. While adhering to the main business of optical fiber and cable, Changfei continues to extend upstream and downstream of the industrial chain of optical fiber preform core raw materials, data center and cable solutions, opening up a new battlefield. Nowadays, people talk about Changfei, which is not only the largest in the industry in the world, but also the representative of Chinese enterprises with the most comprehensive technology.
At present, Changfei has stepped out of China with more heroic steps, and its overseas business has maintained rapid growth. Changfei cooperated with local operators to promote network construction in the Philippines and successfully won the bid for the local network laying project of China Telecom. In 2020, the revenue of Changfei overseas communication network project reached 243 million yuan, an increase of about 304.9% over the previous year. In 2020, Changfei's overseas business will reach 25.57% of the company's overall operating revenue.
Changfei said that in the future, it will be more open, export more advanced technologies and innovative management models, and constantly improve the voice of the global industrial chain.
In the global industrial chain, Wuhan enterprises continue to emerge. Just in the last quarter, Huagong Zhengyuan, the core subsidiary of Huagong technology, announced that the 400g optical module products applied to the next generation data center realized a full series of batch shipments. The enterprise products broke into many countries and regions around the world, such as North America and Europe. The annual production capacity of optical modules exceeded 30 million, becoming one of the largest optical module manufacturers in the world.
The municipal development and Reform Commission said that the enterprise groups led by Changfei and beacon communication have promoted the completion of the upstream, middle and downstream industrial chain of the industry and consolidated Wuhan's important strategic position in the field of optical communication in China.
■ Independent innovation
From downstream to upstream, Wuhan has formed an independent and controllable optical communication industry chain
At present, Wuhan optical communication industry covers upstream optical fiber and cable, midstream optical devices and optical modules, and downstream optical system equipment. At the same time, the means of production and key devices are independently controllable and link up a complete industrial chain.
"Acoustooptic modulator is the core component of pulsed fiber laser. A laser corresponds to a device. The function of this device is equivalent to an optical switch. Without it, the laser can not output light and can not work normally." Zhu Zhigang, general manager of Guangao Technology (Wuhan) Co., Ltd., introduced that the acoustooptic modulator was mainly purchased from abroad, and Guangao has realized large-scale localization in individual fields.
The project of "high beam quality 10000 watt fiber laser core technology and its industrialization" has yielded fruitful results. Ruike, Ruixin and other industrial chain enterprises have developed and produced special optical fibers, preforms and other core components and materials, so as to realize the independent control of the core components of the whole industrial chain, and the technology and production capacity rank first in China and third in the world, It also makes Wuhan one of the few regions in the world with the ability of self-research and self-production of complete core devices of fiber lasers.
This year, the 25G laser chip for elite photoelectric 5G has passed the international reliability test, and officially announced the realization of the whole process R & D and production capacity from laser chip design, epitaxial design and material "growth", wafer manufacturing, chip testing and verification. According to the introduction of the enterprise, after realizing the self-development of core materials, the "growth" time can be controlled within one week, which is 3 months faster than purchasing epitaxial wafers or wafers abroad, which greatly shortens the product iteration cycle.
The upstream enterprises of optical devices such as Yunling optoelectronics and Minxin seized the opportunity of 5G new infrastructure industry. Yongding Guangtong in the middle reaches took off the 5G front transmission module and transmitted the "rod" to Wuhan Feiwo Technology Co., Ltd. this enterprise is the largest supplier of 5G front transmission passive wavelength division equipment of China Telecom. Through Feiwo integration, the equipment equipped with optical module is supplied to the three major operators and installed with base stations Data centers, etc. in this process, psyche, a service provider of testing equipment for optical devices, is also expanding its production capacity.
■ Industry leadership
From products to standards, Wuhan leads the development of domestic laser industry
This year, HGTECH Intelligent Manufacturing Park (phase III of Gedian Park) was put into operation. The project will have the annual production capacity of 3000 high-power laser cutting equipment and 15 production lines of sheet metal processing intelligent factory.
Glass thinner and thinner than hair can also be accurately shaped "unscathed" under laser cutting. As one of the largest suppliers of laser equipment and high-power laser equipment in China, Huagong laser independently developed ultra-thin glass laser cutting technology, with a cutting speed of more than 200 mm per second. After listing, it will be applied to 3C fields such as folding mobile phones and ultra-thin battery substrates. It produces the first FPC (flexible circuit board) full-automatic coating laser cutting machine exported overseas, At present, it is serving the world's largest flexible printed circuit board manufacturing enterprise.
Ruike, the first 10000 watt CW fiber laser in China, broke the international monopoly and formed an independent and controllable laser core industry chain together with Ruixin and other enterprises. Ruike has more than 1500 direct application customers and has been exported to more than 40 countries and regions such as Europe and America. Yan Dapeng, vice chairman and chief engineer of the enterprise, said: "after many years of following, China's fiber lasers can finally run side by side with the world."
Dill laser, which focuses on precision laser processing equipment in the field of solar photovoltaic, is not only listed on the Shenzhen Stock Exchange, but also set up a global R & D center in Israel.
At present, there are more than 200 laser enterprises in Optics Valley alone. The annual output value of the laser industry has reached 100 billion yuan, accounting for about half of the domestic market. It has formed a complete industrial chain and is one of the largest laser equipment manufacturing bases in China.
These listed laser enterprises and rising laser industry clusters are the epitome of Wuhan's laser industry from big to strong. Six years ago, Ruike laser took the lead in drafting China's first fiber laser industry standard in conjunction with Huagong laser; Last year, the international standard "parameter requirements and test methods for industrial fiber lasers" jointly formulated by Huagong laser and others was passed, which is the first international standard for laser products in China; This year, Xiangming laser, an enterprise in the laser cleaning industry, participated in the formulation of national standards.
