Objectives
This module covers 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 a knowledge of the optimisation methods used in optical network design, and investigates the performance of optical fiber communication systems under noise.Learning outcomes
On completion of this module students should be able to:
1. Explain the advantages optical-fibre communication offers over the other established communication systems.
2. Describe the physical properties affecting light propagation in optical fibre.
3. Use mathematical methods to evaluate the performance of the optical-fibre receiver under noise.
4. Describe the various enabling technologies used in modern optical networks.
5. Describe a range of WDM network architectures including broadcast-and-select and wavelength routing networks.
6. Use mathematical methods to apply optimisation techniques in the design of optical networks.

Private study
Students are expected to use private study time to consolidate their understanding of course materials, to undertake preparatory work for seminars, workshops, tutorials, examples classes and practical classes, and also to prepare for in-course and summative assessments.Opportunities for Formative Feedback
Students studying ELEC modules will receive formative feedback in a variety of ways, including the use of self-test quizzes on Minerva, practice questions/worked examples and (where appropriate) through verbal interaction with teaching staff and/or post-graduate demonstrators.Methods of assessment
Coursework
| Assessment type | Notes | % of formal assessment |
| In-course Assessment | Class Test 1 | 30.00 |
| In-course Assessment | Class Test 2 | 30.00 |
| Total percentage (Assessment Coursework) | 60.00 | |
Resits for ELEC and XJEL modules are subject to the School's Resit Policy and the Code of Practice on Assessment (CoPA), which are available on Minerva. Students should be aware that, for some modules, a resit may only be conducted on an internal basis (with tuition) in the next academic session.
Exams
| Exam type | Exam duration | % of formal assessment |
| Standard exam (closed essays, MCQs etc) (S1) | 3 hr 00 mins | 40.00 |
| Total percentage (Assessment Exams) | 40.00 | |
Normally resits will be assessed by the same methodology as the first attempt, unless otherwise stated
