A breakout history of a small chip: Henan, a company that breaks foreign technology monopoly 丨 compete for Henan first

[Dahe Daily · Dahecai Cube] (Reporter Pei Rongguan) On August 28, the theme press conference of the "Ten Years of China · Henan" of the Henan Provincial Party Committee of the Communist Party of China was held in Zhengzhou. The press conference mentioned that in the past ten years, Henan has adhered to the "four aspects", forward -looking deployment of strategic technology R & D projects, integrating the joint research on superior resources, and striving to achieve iterative, subversive, and original scientific and technological achievements.

Among them, researcher An Junming, Henan Shijia, led by the "Light Networks, Light Router Chip and the Key Technology and Industrialization of Formation Board Guide Gallery Chip" project, as one of the top ten scientific and technological innovation achievements, and was focused on it. The press conference mentioned that the project broke the technical monopoly abroad of this type of chip, realized the autonomous and controllable optical chip in my country, and made important contributions to the construction of "Broadband China".

The reporter learned from Shijia Photon that the project mainly contains more than 20 product categories: PLC light divisions chip and AWG chip series. In 2017, they won the second prize of the National Science and Technology Progress Award in 2017.

Looking back now, what kind of story has happened behind this?

Cooperation of being moved

Pour the time back to 2010. At that time, Zhengzhou Shijia Communication (Shijia Optical Control shareholder) was seeking business transformation and aiming at the high -end field of the optical communications industry -optoelectronic chip. However, the core technologies at that time were in the hands of foreign companies. Ge Haiquan, the chairman of Shijia Communication, looked at the eyes and was anxious to seek technical cooperation across the country, and was determined to create a new world in the field of PLC chips.

At this time, in Beijing, 700 kilometers away, the team of the Institute of Semiconduction of the Chinese Academy of Sciences has been studying in the field for more than ten years. It has reached the barrier of technological transformation and is looking for a platform for cooperation. It was moved by Ge Haiquan's perseverance. As soon as the two were shot, they officially opened the research and development cooperation of academic and enterprises in the field of optoelectronic chip.

In general, the chip that distributes the optical signal is popular. Suppose a total of 32 households in a community and a building, from the computer room to the user of each unit, if you do not use the optical router chip, you need to lay 32 fiber optic cables to the unit. Essence After using the sedentary chip, only one 32 -channel PLC chip is required to allocate the optical signal to 32 users. process.

Wu Yuanda, deputy general manager of Shijiaguangzi, told Dahe Cai Cube reporter that after such a small chip independently developed, the price dropped from nearly 200 yuan to more than ten yuan.

Breakout from running to measuring and running

Why is it so difficult to develop a small chip?

Wu Yuanda once told Dahe Cai Cube reporter that the cost of chip technology in the early stage is very large. On the one hand, the chip production equipment has a large investment and high operating costs; on the other hand, the development cycle is long. It takes 3 to 5 years, or even longer. For ordinary enterprises, especially private enterprises, in addition to taking high R & D investment, it is also necessary to prepare for the risk of renewal iteration.

At the same time, many foreign optoelectronic chips have been very mature, and the existing technology gap sets a natural market barrier. How to leverage the original market is also the "blockbuster" that newcomers must encounter.

Fortunately, relying on the strong research and development foundation and technical accumulation of the Institute of Semiconductor Research of the Chinese Academy of Sciences, this "breakout war" has not been spent too long.

In the second year of the cooperation between the two parties, Shijia Photon officially released the PLC light divisions chip to become the first Chinese in China. At that time, it was the only company in China that could mass -produce the chip. The situation.

While the PLC seminars chip achieved preliminary benefits, the team continued to deploy the development of AWG chips (the chip that allows a optical fiber to transmit multi -path signal, which can eventually realize the transmission of optical fiber network without increasing optical fiber laying. The rate is mainly used in the backbone network, urban area network, high -speed data center, and 5G fields) and DFB laser chips (distributed feedback laser, which is widely used in wireless, fixed network access, urban transmission and other fields). While achieving the entire chip independent research and development, some segments have also achieved the rise of technology from long -term "following" to "running", and promoted the independence and self -reliance of domestic optoelectronic chips.

There is such a statement on the official website of the Institute of Semiconductor Research of the Chinese Academy of Sciences: After more than ten years of concentration, the project team has made a comprehensive breakthrough in the design, process and industrialization of the light divisions and AWG chips. N (N maximum can reach 128) The PLC light divisor chips and AWG chips of more than 20 varieties of two series of two series are built in the country's largest optical railway and AWG production line. In the past three years New profits are 85 million yuan, and new sales of enterprises have been promoted by more than 5 billion yuan, and new profits are 400 million yuan. Products are widely used in the construction of FTTH and optical transmission networks at home and abroad, breaking the monopoly of my country's light -dividing router chips, filling domestic gaps, and making important contributions to the successful implementation of the "Broadband China" strategy.
