The spotlight is on Eoptolink Technology Inc.,Ltd., a leading Sichuan-based stock, as it faces both a technological milestone and potential export headwinds reminiscent of a "gray rhino" event.
A patent for a MEMS module drive system has been uncovered. Records from the national intellectual property office show that Eoptolink Technology Inc.,Ltd. filed a patent application titled "A MEMS Module Drive System," with a publication date of August 4, 2026. The patent abstract describes an invention in the field of electrical drive technology, featuring at least one drive board with multiple driver sub-units, each containing multiple output channels. It includes at least one MEMS module comprising multiple MEMS mirror units, each with multiple control ports. An electrical connection substrate with a wiring structure connects the input side to the output channels and the output side to the control ports. Output channels with the same number across different driver sub-units within the same drive board form a target channel group for a MEMS mirror unit, with the wiring structure mapping each control port to a corresponding output channel in the target group. This design reduces update timing deviations between multiple control ports at the hardware level, enhancing drive signal synchronization, according to the patent office.
In simpler terms, this technology enables thousands of tiny MEMS mirror units to operate in perfect sync at the hardware level, which is critical for improving the precision and efficiency of all-optical switching. Business records indicate Eoptolink Technology Inc.,Ltd. is primarily engaged in the computer, communication, and other electronic equipment manufacturing industries, with a registered capital of 1,394,256,684 yuan. The company holds 249 patent records, covering areas such as optical modules, their manufacturing methods, link optimization techniques, and battery compartment locking structures. Notably, in July alone, Eoptolink Technology Inc.,Ltd. published eight new patent filings, signaling an accelerated pace of technological development.
Long-term optimism surrounds optical modules. Almost simultaneously with the patent disclosure, market reports emerged from across the Pacific suggesting that the U.S. Federal Communications Commission (FCC) is drafting a ban to prohibit the import of new models of Chinese data center components, including optical modules. Eoptolink Technology Inc.,Ltd. focuses on the research, development, production, and sales of optical modules for all series of optical communication applications. It was among the first companies globally to mass-produce and deliver 1.6T optical modules. In 2025, over 96% of its revenue came from overseas markets. Following the news, optical module concept stocks collectively declined on August 5. Eoptolink Technology Inc.,Ltd. shares opened lower but recovered somewhat, closing down 5.29%. However, selling pressure returned on August 6. The stock continued its downward trend, hitting a low of 397.09 yuan per share in early trading before rebounding to close down 0.57% at 421.87 yuan per share, giving it a total market capitalization of 588.2 billion yuan.
Despite the consecutive two-day decline, trading volume remained substantial. The intense battle between bullish and bearish forces suggests market confidence in the long-term prospects of this Sichuan-based stock leader. Regardless of how market rumors evolve, the pace of technological advancement in the industry remains undeterred. The optical module sector is accelerating its technology iteration, with transmission speeds moving from 800G to 1.6T and solutions like CPO (Co-Packaged Optics), NPO (Near-Packaged Optics), and silicon photonics integration undergoing continuous validation. In its investor relations activity records released on July 20, Eoptolink Technology Inc.,Ltd. revealed that 800G optical module shipments have grown significantly this year, becoming the company's main product. 1.6T optical module shipments in the second quarter rose notably compared to the first quarter, with volume expected to accelerate further from the third and fourth quarters. For forward-looking institutional investors, the commercialization timeline for new technologies like NPO is another key focus. Eoptolink Technology Inc.,Ltd. stated that dedicated teams are continuously advancing NPO product development, with order delivery needs expected in the second half of 2027 and shipment volumes to gradually increase from 2028. Regarding silicon photonics technology, the company's team size and capabilities are steadily improving, and its market share in silicon photonics products is also growing. Industry insiders commented that regardless of whether the ban is implemented, it will have little impact on the industry's technological direction. The domestic optical module market also has strong demand, and advanced technology paths like NPO and CPO are progressing steadily.
