Course Overview
The NCTI DAA and High-Split Networks course is an advanced engineering overview designed for broadband professionals spearheading the transition to 10G.
As bandwidth demands skyrocket, operators are moving away from centralized headend architectures. This course explains how Distributed Access Architectures (DAA) and High-Split configurations unlock massive capacity advancements in existing Hybrid Fiber/Coax (HFC) networks—without the need for a complete rebuild.
Students will explore the critical shift of moving PHY layer functions to the node (Remote PHY), the mechanics of DOCSIS 4.0, and the specific testing requirements for Optical Fiber, Ethernet, and RF Plants in this new environment.
Who Should Attend:
- HFC Network Engineers
- System Designers
- Headend and Maintenance Technicians
- Technical Operations Managers
What You Will Learn
Upon completion, students will understand the architectural evolution of the cable industry and the practical testing methods required to validate next-generation networks.
Core Competencies:
- Architectural Evolution: Define DAA components, including Remote PHY Devices (RPDs) and Converged Cable Access Platforms (CCAP), highlighting the power and space-saving benefits.
- Spectrum Expansion: Compare High-Split configurations vs. legacy splits, and distinguish between Full Duplex (FDX) and Extended Spectrum DOCSIS (ESD).
- Fiber Testing: Master testing methods for DAA fiber links using OTDRs, Optical Loss Test Sets, and MPO testers.
- Ethernet Verification: Utilize SFP modules and BERT (Bit Error Rate Testing) to evaluate network capacity and signal integrity.
- RF Plant Validation: Perform sweep tests adapted for High-Split networks and mitigate RF Leakage in compliance with FCC aeronautical frequency regulations.
