In this paper, we will provide a backwards, current, and forward-looking perspective around this monumental broadband milestone. The operationalizing of new technology, in particular with the nature of innovation inherent in D4.0 FDX, builds on previous transformational change introduced with distributed access architecture (DAA) and the virtual cable modem termination system (vCMTS). Unique development, integration, and field challenges drove creative plans and tactics across teams to meet the 2023 launch target and prepare for scalability in 2024. The path ahead requires a close look at the current strategy and the foundation it provides, and subsequently the relationship among performance, product speeds, capacity, and spectrum management to plan effectively for the multi-year migration ahead.
In this paper, we will detail that journey, including: • Capacity, Speed, Spectrum, and Network Strategy • FDX Traffic and Utilization • Hardware (HW) and software (SW) Integration, Test, and Trial Methodology • Key Observations, Field Measurements, and Lessons Learned • Future Feature and Technology Roadmap
