Module summary
The teaching and assessment methods shown below will be kept under review during 2020-21. In particular, if conditions allow for alternative formats of delivery, we may amend the timetable and schedule appropriate classes in addition to (or in place of) the Online Learning Workshops. For Semester 2 (from January 2021), we anticipate that this will be most likely, in which case online teaching will be substituted for traditional face-to-face teaching methods, including lectures and practical classes. ‘Independent online learning’ will involve watching pre-recorded lecture material or screen-casts, engaging in learning activities such as online worked examples or remote/virtual laboratory work, etc. Students will be expected to fully engage with all of these activities. The time commitment for independent online learning, and also the frequency and duration of Online Learning Workshops, are approximate and intended as a guide only. Further details will be confirmed when the module commences.Objectives
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 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
