DOCSIS Network Overview

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

COURSE DESCRIPTION:

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

COURSE OVERVIEW:

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.

COURSE OBJECTIVES:

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

COURSE OUTLINE:

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