VNET Fiber Invests in Secure Agentic AI With Calix One To Extend an 87 NPS Advantage and Expand into MDU
Building on a 15-year partnership with
This strategy builds on 15 years of leveraging the Calix platform and SmartLife™ to win strong subscriber loyalty, earning a Net Promoter Score℠ (NPS®) of 87. With SmartHome™, VNET Fiber achieved 660 percent residential subscriber growth in just over two years and a nearly 10 percent average revenue per user (ARPU) jump year-over-year through personalized, value-based offers built on a secure residential managed service. By deploying SmartBiz™, VNET Fiber has already achieved 133 percent of their annual SMB subscriber goal for the year, outperforming targets year over year since 2024 while giving small businesses a fully managed way to secure and operate their networks at scale.
VNET Fiber is now advancing to the next phase of their success: expanding to serve MDUs while adopting secure agentic capabilities with the Calix One platform. With SmartMDU, VNET Fiber is extending a proven growth strategy into a high-opportunity market, enabling residents to benefit from the same experience-led approach that has driven their single-family residential and business subscriber growth. At the same time, Agent Workforce Cloud will help the VNET Fiber team proactively identify expansion opportunities and service issues while lowering OPEX. Supported by agentic workflows, VNET Fiber teams can stay focused on delivering exceptional experiences.
