Calix 50G-PON Extends Platform Advantage To Scale Services Without Rebuilding Networks
Today, Calix, Inc. (NYSE: CALX) announced that it is extending the Calix One platform into the next era of high-capacity fiber innovation, enabling service providers to evolve their networks to support future residential, business, and multi-dwelling unit (MDU) growth with secure connectivity. By supporting standards-based 50G-PON within its AI-native platform, Calix will deliver a practical path to deliver capacity where it matters without disrupting existing operations.
Service providers recognize that high-capacity fiber is critical for staying competitive, yet legacy access architectures often create complexity, slow service delivery, and increase operating costs. With Calix One, providers can seamlessly introduce 50G-PON as part of a unified, converged passive optical network (PON)—streamlining operations, expanding bandwidth across all markets, maximizing fiber investments, and reducing total cost of ownership. 50G-PON supports the delivery of secure, highly available, low-latency services for businesses, mobile backhaul, smart infrastructure, multi-tenant, and wholesale market deployments.
The momentum for 50G-PON on the Calix One platform continues to grow as providers evaluate the lasting impact of their network choices—as demonstrated by successful trials in North America with ALLO Communications and Brightspeed.
Calix 50G-PON will enable incremental capacity growth and protect fiber investments by:
- Expanding high-performance network capacity while preserving existing PON services. The AXOS E7-2 50G-PON line card will offer a scalable, standards-based solution that supports all services on a single network. Compatible with 50G-PON, XGS-PON, and GPON, the line card will deliver flexibility to add new services as needed, operate more efficiently, and generate more revenue.
- Integrating 50G-PON into the AXOS operating system service providers already use. With AXOS—the software-defined operating system for Calix E-Series access appliances—50G-PON will extend a modular, disaggregated access architecture to ultra-high-capacity services. This will enable providers to deploy, operate, and evolve 50G-PON alongside existing services without added complexity or silos.
