SDH Transmission Systems

Course Objectives:

This tutorial course provides a thorough overview on several topics:

  • Basics of optical transmission systems (WDM, OTDM)
  • Advantages and drawbacks of PDH and SDH systems
  • Operation principles of PDH and SDH with emphasis on practical aspects
  • The SDH frame structure, pointer justification mechanism, overhead and multiplexing schemes
  • Functions and system-level description of SDH equipment (regenerators, terminal and add-drop multiplexers, digital cross-connects)
  • Several examples of network applications of SDH equipment
  • SDH networks architectures
  • Traffic protection and restoration in SDH networks
  • Techniques for broadband data transport over SDH (ATM, IP, VCAT, LCAS, GFP, GbE)
