Nvidia GB200 chip using copper cable connection has become the focus of the market.
After trading on May 17, Shenyu shares issued a notice that the company's stock prices have risen greatly recently, the turnover rate is high, there is a situation of overheated market sentiment, and there may be irrational speculation.
On May 16 and 17, Shenyu shares rose more than 15% in a row, and this week it rose by 57%.Crouchingtigerhiddendragonswordofdestiny2016. the weekly increase of 19% ranked first in A-shares, and market sentiment was high.
Despite the 18 concepts involved, Shenyu is not a hot stock in the market, and its share price, which had been trading sideways for more than six years before the market rose, suddenly led the rise, thanks to a hot company around the world.
Nvidia concept helps
In March this year, Nvidia GTC conference launched the cabinet-level solution GB200NVL72, in which the communication between cabinets adopts the optical interconnection mode of IB network architecture, and the speed of servers and switch ports in GB200 architecture has been greatly increased. Among them, the copper connection of GB200 chip has become the focus of the market.
High-speed copper connector is a kind of connector used to transmit high-speed and high-frequency signals. it uses copper cable as transmission medium to connect components, equipment or systems together. it has the characteristics of high transmission bandwidth, good impedance consistency and strong anti-interference ability. it is widely used in data center, communication, aerospace, automobile and other fields.
According to the analysis, compared with the optical module, the cost of the copper high-speed connection is about 1 / 10 of the optical module, the power consumption is about 1 / 2 of the optical module, and the delay is about 1 / 10 of the optical module.
According to LightCounting, sales of high-speed copper cable are growing as server connections and as interconnections in decoupled switches and routers. It is estimated that high-speed copper cables will grow at a compound annual growth rate of 25% from 2023 to 2027, and shipments of high-speed copper cables are expected to reach 20 million by 2027.
On April 25, Shenyu shares ushered in two major events.
The first-quarter results announcement issued by the company that night said that it had achieved revenue of about 1.Crouchingtigerhiddendragonswordofdestiny20168.6 billion yuan, an increase of 33.27% over the same period last year; the net profit attributed to shareholders of listed companies was about 50.24 million yuan, an increase of 442.54% over the same period last year. Fukai Finance notes that the extraordinary performance in the first quarter has almost equaled the net profit for the whole of 2023.
The other is to add the concept of "copper cable high-speed connection". According to the information of Shenyu's 2023 annual report, with the explosive growth of AI artificial intelligence, the market of AI learning computing server is booming, and the company's DAC copper connection cable can be widely used for internal data transmission in AI servers.
Driven by two favorable factors, Shenyu shares closed the 20cm trading limit in less than 20 minutes after opening trading on the 26th.
On May 13, the concept of high-speed copper cable, which had been slightly consolidated for several days, came into force again. Shenyu shares rose more than 14% in intraday trading, and related concepts such as Lixun Precision, Huafeng Technology, AVIC Optoelectronics, Wall Nuclear Materials and so on.
After May 22, Nvidia will release a performance report, and the mass production time of GB200 chips will once again become the focus of market attention.
Four major growth points of power
At present, the market demand for high-end servers represented by AI servers is surging, and high-speed data lines will continue to grow at a high speed. Shenyu said that it will further increase the market share of high-frequency and high-speed cables in the future.
Fukai Finance noted that aerospace, navigation, medical devices and automobiles were also the focus of Shenyu's 24-year efforts.
Shenyu said that for many years, China's stable phase microwave RF coaxial cable basically depends on imports. After years of continuous development of the company's R & D investment, a number of stable phase microwave coaxial RF cables have been adopted by large group enterprises. the company will closely follow the import substitution strategy of national key military parts.
In the field of medical devices, it is still dominated by multinational enterprises and some Sino-foreign joint ventures, and the terminal customers of downstream medical devices have an urgent demand for domestic substitutes. China's huge population base and the trend of gradual aging make China's medical device market have great potential.
In terms of the cable system for high-end medical devices, Shenyu successfully developed the outer diameter 0.29mm endoscope module cable, which broke through the welding technology of the very small lens module in the industry; intervened in the small ultrasonic probe wire to achieve mass production, and a number of products passed the strict testing of Mindray Medical, the leading company in the industry. In the field of nuclear magnetic resonance coil, the ultra-fine semi-rigid wire produced by the company has realized import substitution and successfully entered the supply chain system of leading enterprises at home and abroad.
With the increasing degree of vehicle intelligence, there are more and more types and application scenarios of automobile cables, such as autopilot intelligent domain, 360 °image transmission, vehicle interconnection, vehicle multimedia applications and so on. Shenyu said that the automotive communication transmission components produced by the company are used for the transmission of signals such as main control screen, reversing image, Wi-Fi, Bluetooth, radar, etc. at present, the terminal customers served include Toyota, BMW, ideal, Ulay, Zero and so on, and are gradually realizing mass production and delivery.
However, at present, the concentration of the international radio frequency communication cable market is relatively high, with companies such as Belden, Gore, Habia, Times, Nexans, Sumitomo and Hitachi occupying most of the market. The domestic RF coaxial cable industry started relatively late, the overall technical level is relatively low, and the share of very fine RF coaxial cable and phase-stabilized microwave RF coaxial cable is not high.
