A bipartisan Senate bill would ban Chinese optical transceivers from national-security systems.

McCormick, Cornyn, Fetterman and Gallego introduced a bill barring federal procurement of transceivers from InnoLight, Eoptolink, their affiliates and any company War or Commerce designates, including parts using their firmware, after a five-year transition. InnoLight is the world's largest transceiver maker and already on DoD's Chinese military company list. Industry groups warn the ban could slow US data center buildouts that depend on these optics, which is the same tension as every other export control: the security case and the buildout case point opposite directions.
