We are aiming for an incremental return to campus in accordance with guidelines provided by NSW Health and the Australian Government. Until this time, learning activities and assessments will be planned and scheduled for online delivery where possible, and unit-specific details about face-to-face teaching will be provided on Canvas as the opportunities for face-to-face learning become clear.

Unit of study_

ELEC5511: Optical Communication Systems

Optical telecommunications has revolutionized the way we receive information and communicate with one another. It underpins broadband access networks, data centres, computer networks, and the next generation 5G. This course will provide an understanding of the fundamental principles of optical fibre communication systems. This includes optical fibre propagation characteristics and transmission properties. Then light sources are considered and the fundamental principles of laser action in semiconductor and other lasers, including nanotechnology for quantum well lasers, tunable lasers, optical amplifiers, and optical transmitters based on semiconductor and electro-optic modulation techniques. On the receiver side, photodetection principles, nanotechnology photodiode structures, and optical receiver sensitivity will be presented. Other aspects such as photonic integration, as well as multi-channel multiplexing techniques will also be discussed. Finally, the complete optical fibre communication system will be studied to realise high capacity digital transport for data centres, local area networks and multi-channel optical systems.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

Special consideration

If you experience short-term circumstances beyond your control, such as illness, injury or misadventure or if you have essential commitments which impact your preparation or performance in an assessment, you may be eligible for special consideration or special arrangements.

Academic integrity

The Current Student website provides information on academic honesty, academic dishonesty, and the resources available to all students.

The University expects students and staff to act ethically and honestly and will treat all allegations of academic dishonesty or plagiarism seriously.

We use similarity detection software to detect potential instances of plagiarism or other forms of academic dishonesty. If such matches indicate evidence of plagiarism or other forms of dishonesty, your teacher is required to report your work for further investigation.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.
