As part of the FCC's ongoing, phased Conditional Approval process, the latest approval notice—combined with prior authorizations—now covers all Calix gateway appliances, giving customers full confidence to continue ordering, deploying, and supporting them across any market

Calix, Inc. (NYSE:CALX) today announced that the Federal Communications Commission (FCC) Public Safety and Homeland Security Bureau have recognized Conditional Approval granted by the U.S. Department of War (DoW). The latest action—combined with prior authorizations—means all Calix gateway appliances are now covered under the FCC's ongoing, phased approval process, permitting their continued importation, sale, and deployment. As a result, service providers can confidently deploy Calix GigaSpire® and GigaPro® gateway appliances—integrated with the AI-native Calix One™ platform—to deliver differentiated experiences across any market.

The latest Conditional Approval exempts Calix gateway appliances from the FCC's Covered List and removes the associated restrictions. Existing FCC equipment authorizations remain valid, and Calix will continue to deliver software, security, and firmware updates across its installed base. The company will also keep complying with and participating in the FCC's approval process as its gateway appliance portfolio expands to address customer needs.

With a robust U.S. manufacturing footprint, Calix not only satisfies regulatory requirements under Broadband Equity, Access, and Deployment (BEAD) and other federal funding programs but also reinforces its ongoing supply chain integrity and compliance—enabling service providers to meet federal standards and deliver uninterrupted services to their subscribers.

John Durocher, chief operating officer at Calix, said: "Our trusted partnerships with service providers are grounded in more than 26 years of understanding their workflows and business models. This approval underscores our ongoing commitment to security and enables us to continue the seamless delivery of agentic capabilities through the AI-native Calix One platform—helping customers transform operations and accelerate experiences to compete and win."
