|Brief Handbook Description:||This course will provide an understanding of the fundamental principles of optical fibre communication systems. It commences with a description of optical fibre propagation characteristics and transmission properties. We will then consider light sources and the fundamental principles of laser action in semiconductor and other lasers, and also the characteristics of optical transmitters based on semiconductor and electro-optic modulation techniques. The characteristics of optical amplifiers will also be discussed. On the receiver side, the principles of photodetection and optical receiver sensitivity will be discussed. Other aspects such as fibre devices and multiple wavelength division multiplexing techniques will also be discussed. Finally, the complete optical fibre communication system will be studied to enable the design of data transmission optical systems, local area networks and multi-channel optical systems.|

Attributes listed here represent the key course goals (see Course Map tab) designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment tabs for details of how these attributes are assessed.
|Attribute Development Method||Attribute Developed|
|Design and problem skills are developed in assignments nad computer laboratories. This inlcudes the optimum design of laser-based optical transmitters and a complete optical fibre communication system.||Design (Level 4)|
|Gain an understanding of the principles of optical fibre communication systems. including optical fibre propagation characteristics and transmission properties, light sources and the laser action, optical transmitters, optical amplifiers, photodetection, and multiple wavelength division multiplexing techniques .||Engineering/IT Specialisation (Level 4)|
|Gain a detailed understanding of the fundamental concepts in fibre optic communications and utilise this in the design of complete optical communication systems to enable data transmission optical systems, local area networks and multi-channel optical systems.||Maths/Science Methods and Tools (Level 4)|
|In addition to the undersatnding the text and lecture note framework, students need to do additional information searches to obtain necessary supplemantary material.||Information Seeking (Level 2)|
|Students work in groups in laboratory work, and they need to communicate their work via a group laboratory report.||Communication (Level 2)|
|Group work in labs and tutorials.||Project and Team Skills (Level 2)|
For explanation of attributes and levels see Engineering & IT Graduate Outcomes Table.
Learning outcomes are the key abilities and knowledge that will be assessed in this unit. They are listed according to the course goal supported by each. See Assessment Tab for details how each outcome is assessed.Design (Level 4)
Final Exam: Exam - 2 hours, covering all aspects of the unit of study.
Assignments comprise design and analysis of optical fibres, laser transmitters, optical receivers, and optical communication systems.
Laboratory sessions comprise computer aided design and simulation modules.
Late hand-in penalty is 20% per working day.
There may be statistically defensible moderation when combining the marks from each component to ensure consistency of marking between markers, and alignment of final grades with unit outcomes
