Chinese Optical Transceiver Makers Plummet on US Ban Draft
Shares of Zhongji Innolight, a Chinese manufacturer of optical transceivers, plunged up to 16% on Wednesday following reports that the United States is drafting a ban on Chinese-made optical transceivers in data centers supporting artificial intelligence (AI) development. The proposed ban, reportedly initiated by the Federal Communications Commission (FCC), aims to halt imports of new models of optical transceivers—devices that convert data into light pulses and back—to prevent Chinese firms from stealing data or installing malware. The news triggered a sell-off in Chinese data center component companies, reflecting heightened US-China tech tensions. The ban is part of broader US efforts to restrict Chinese access to advanced technologies amid the AI race.
