DOCSIS Network Overview

DOCSIS Network Overview


This is an e-learning course. Students get access to the content for 6 months.



Students taking the DOCSIS Network Overview training course will learn about DOCSIS basics and the physical network it runs on.



Students enrolled in the DOCSIS Network Overview training course will learn about DOCSIS basics, modem operations, and the digital modulation schemes employed by DOCSIS. The Hybrid Fiber/Coax (HFC) network, which DOCSIS runs on in a cabled world, is also explored. The course provides a foothold to a deeper dive into DOCSIS.



Upon completing this course, students will be able to:

  • Discuss how upstream RF levels are determined and maintained, and the impact of operating modems in a shared network.
  • Explain how the DOCSIS modem operates in the transmission path
  • Describe the role of cable and connectors in a distribution system
  • List and describe the role of passive signal transmission components in a distribution system
  • Describe different distribution system amplifiers and identify basic amplifier components
  • Explain basic system powering theory, identify power supply components and basic operation, and describe underground and aerial installations
  • Describe how a ring architecture using fiber-optic cable can maintain reliability
  • Recognize the HFC progressions that have brought fiber-optic cable closer to the customer premises
  • Understand why the broadband cable industry is developing its own PON (passive optical network) standard
  • Describe the primary digital modulation schemes used in broadband cable networks


  • Considering DOCSIS in the Network
  • Obtaining DOCSIS Single Carrier RF Operating Parameters
  • Examining Distribution System Equipment
  • The Evolving HFC Network
  • Describing Digital Modulation Schemes
