CITIC Securities said the likelihood that the FCC’s rumored ban on Chinese optical modules will be implemented in its current form is low, noting U.S. market dependence on Chinese modules is a major barrier.

High China–U.S. interdependence in the optical-communications supply chain means such restrictions would raise procurement costs for North American cloud providers and delay their deployment schedules as they decouple from large-scale Chinese deliveries. CITIC said leading Chinese module vendors already have integrated advantages across technology iteration, mass production and client responsiveness in AI high-speed interconnects, leaving the ban subject to significant practical industry resistance.
