Module summary

This module presents the essential elements of modern optical networks. The module looks at the development of wavelength-division multiplexing (WDM), the most popular, bandwidth-rich contemporary approach, its enabling technologies, node and network architectures. It provides the students with the essential of knowledge of the optimisation methods used in optical network design.

Objectives

- To teach the student the essential elements of modern optical networks

- To investigate the performance of optical fiber communication systems under noise

- To understand the principle of operation of erbium-doped fiber amplifiers (EDFA) and their use in optical networks

- To understand the evolution of modern optical networks

- To study the enabling technologies, node architectures and network architectures of wavelength-division multiplexing (WDM) networks

- To study the use of optimisation methods in optical network design
