Coherent jumped 12.35% and Applied Optoelectronics (AAOI) gained 19.44% the same day.

FCC Drafts Chinese Optical Transceiver Import Ban
Reuters reported on August 4 that the Trump administration is preparing measures to ban imports of Chinese optical transceivers. The Federal Communications Commission (FCC) is drafting legislation to ban imports of new Chinese optical transceivers to protect critical infrastructure supporting the AI boom, with potential announcement by year-end.
Optical transceivers are core components in fiber optic-based communication networks that convert electrical signals to optical signals and vice versa for transmission and reception. They serve as translators connecting data center servers to fiber optic cables. Their importance has grown as AI data centers increasingly struggle to handle massive data flows with traditional copper wiring alone.
The import ban is being pursued for security purposes to prevent Chinese hardware manufacturers from installing malicious code or collecting data through optical transceivers in US data centers. The FCC added Chinese companies Huawei and ZTE to its covered list of companies posing threats to US national security in 2021. In December and March, the agency included DJI and multiple other Chinese companies on the list to ban imports of Chinese drones and routers.
Zhongji Innolight Holds 27% Global Market Share
If the legislation is implemented, Big Tech companies will need to purchase components from US competitors instead of Chinese optical transceivers. According to market research firm Counterpoint Research, Chinese company Zhongji Innolight currently ranks first in the global transceiver market with a 27% market share. The company has secured multiple Big Tech firms as clients, with 90% of its revenue generated from regions outside China. Zhongji Innolight was added to the US War Department's (formerly Department of Defense) list of Chinese military support companies in June.
