The U.S. Federal Communications Commission voted to tighten security rules for undersea internet cables and to block Chinese and other foreign-adversary equipment from key parts of those systems. The order would require licensing for submarine line terminal equipment (SLTE), the gear that links submarine cables to U.S. terrestrial networks, and would streamline approvals for operators that meet security and oversight conditions. The rules also expand scrutiny of equipment suppliers and third-party service providers tied to cable operations.
Why it matters: Undersea cables carry most of the world's internet traffic, so new security rules for the equipment and operators behind them matter well beyond telecom companies. Cable operators, vendors, and policymakers should review the new licensing and procurement restrictions, especially around foreign-sourced equipment and service providers.
