FCC final rule stops short of directly targeting major Chinese optical module makers
The U.S. Federal Communications Commission has formally released its final rule on equipment authorization and communications supply chain security, with publication set for Sept. 11 and the measure taking effect 30 days later. The outcome was less severe than many in the market had feared: core Chinese companies in the optical communications supply chain, including Eoptolink, Innolight, Suzhou Dongshan Precision Manufacturing and TFC Communication, were not directly placed on an FCC restriction list. The report says the immediate threat of a blanket ban has not materialized, even after the FCC moved optical transceiver modules into the Cover List control scope on July 22 and a draft proposal surfaced on Aug. 4 suggesting a ban on imports of new Chinese optical transceiver models. Still, the broader contest over supply chain security remains in place. A second and arguably deeper shift is unfolding at the same time. Co-packaged optics, or CPO, is moving toward mass production, led by companies such as NVIDIA and Broadcom. The article argues that while geopolitical restrictions may pressure Chinese suppliers, the more serious long-term challenge lies in the transition from pluggable modules to integrated optical-electrical architectures, especially as overseas foundries have already built out their positions in silicon photonics manufacturing.
