The NCTI® DAA and High-Split Networks course provides the fundamental features of distributed access architectures (DAA) and high-split configurations,which enable capacity and performance advancements in hybrid fiber/coax (HFC) networks without requiring a complete rebuild. DAA streamlines the integration of advanced technologies like DOCSIS 4.0 and enhances network management and signal performance, enabling the effective deployment of high-split configurations. Together, these technologies create a broadband infrastructure built for the future.

This course explores the evolution and current state of HFC networks, and their transition to next-generation systems. It also explains the roles of DAA and high-split designs in shaping the future of the cable industry, as well as the critical factors to consider when implementing them. Students will gain practical knowledge of DAA and high-split testing requirements and learn to use specialized equipment to test various components of the network, including optical fiber, Ethernet, RF plant, and coaxial systems.
