Module Description: Fiber Optics and Switching Networks

Hours of Instruction: 80 hours
Module Length: 10 days (not including labs)
Required Textbooks:

Jeff Hecht, Understanding Fiber Optics
Roger L Freeman, Telecommunication System Engineering

This module is the introduction to switching systems and optical signal transport. The switching section is composed of three major components: Networks, switching, and signaling. We discuss the operation and design of different types of networks and switching systems. Analog, digital, packet, and optical switching are all considered. In-class minor projects are used to consolidate concepts learned in lectures. We discuss switching as it developed through different phases: manual, electromechanical, electronic, and optical. The functions are the same, but are done using different technologies.

The optical section will provide a practical introduction to the basic principles of optical fiber systems and networks. The course will emphasize the physical properties and operation of components that comprise optical systems (fiber, semiconductor lasers, photodetectors, etc.), optical networking (SONET, etc.), and interfacing optical and electrical networks. The basic elements of optical network operation and design will also be discussed.

Module Objectives:

Students should be able to accomplish the following after attending this module:

  • Explain the basic switching concepts in data networks.
  • Describe the use of switching fabrics and switching control systems.
  • Understand the concepts of fiber transmission and signal detection.
  • Utilize the key concepts, design principles and functions of optical network architectures in a network. design.
  • Explain the function of each component within an optical network.
  • Recognize switching vulnerabilities and be able to apply appropriate security to protect a network from cyber attacks.

Module Outline:

  • Session 1: Computer Networking Architecture and Services
  • Session 2: Telephony, Traffic, and Communication Networks
  • Session 3: Switching Fundamentals, Fabrics, and Control
  • Session 4: Signaling, Signaling System 7, and Intelligent Network
  • Session 5: Transmission, Technology Impairments, Multiplexing, and Long-Distance Networks
  • Session 6: Introduction, Basics of Fiber Optics, and the Fiber
  • Session 7: Light Sources, Transmitters, and Receivers
  • Session 8: Passive and Active Components
  • Session 9: Why Use Fiber Optics
  • Session 10: Optical Networks
