US Preparing First Import Ban on Chinese Datacenter Transceivers

The FCC is drafting a ban on importing new Chinese optical transceivers — the photonic modules that carry high-speed data between servers inside datacenters. Reuters reported the move on August 4, 2026. Officials aim to publish it this year, though it may change or be dropped. Chinese firms dominate the global transceiver market. Beijing's embassy said China "will take all necessary measures" in response.
