The U.S. Federal Communications Commission is drafting a rule that would block Chinese optical modules from entering American data centers, according to Techub News. Optical modules are critical components for data transmission inside data centers. Chinese manufacturer Zhongji Innolight currently holds roughly 27% of the global market for these devices. In a report cited by Techub News, Counterpoint Research says Western suppliers cannot quickly fill a supply gap, and it would take approximately 12 to 24 months to increase production capacity. As a result, hyperscale cloud operators including Amazon, Microsoft, Meta and Google could face serious effects on the progress and cost of building out AI infrastructure. The potential restrictions could hit both the speed and the budget of cloud expansion for the largest U.S. technology companies. The Techub News brief credits CryptoBriefing as the source. The draft rule is still in preparation, and no final details have been provided in the report.
