FCC mandates SLTE licensing and China equipment ban for submarine cables

The rules create a two-track approval process: operators certifying U.S. headquarters, incident-free history, and no foreign adversary gear receive expedited review, while others face full national security scrutiny. SLTE licensing directly targets the segment converting optical signals to terrestrial networks, a point of concentrated interception risk previously outside explicit FCC licensing. Procurement records show prior exclusions of Huawei, ZTE, China Telecom, and China Mobile; the new order extends the prohibition to any entity in China regardless of corporate structure.

Technical evidence from Salt Typhoon operations and documented Russian submarine activity near UK cables demonstrates repeated attempts to access or map these systems. Independent analyses from cable landing station audits confirm that SLTE configurations determine encryption handoff points and monitoring access, yet no public CVE database tracks SLTE firmware exposures at scale. Official statements emphasize espionage prevention while procurement data reveals the parallel goal of accelerating U.S. AI-driven capacity expansion.

The policy aligns with existing Team Telecom reviews but adds ongoing compliance reporting absent from earlier cable licenses. Next steps include publication of the final order, followed by a 180-day window for existing operators to apply for SLTE licenses or demonstrate exemption eligibility.
