Unit Information

Why is this unit important?

The internet is largely based on signals of light travelling across the globe, often with intensities brighter than the sun. The unit starts with a discussion about how we produce light and then modulate it to encode digital signals. This could be as simple as blinking the light on and off, but in reality even that quickly becomes complex. The next challenge involves getting the signal from A to B and being able to decode the information after receiving a very noisy and faint signal. Even then, a single communication link is not enough: it must be so reliable and so fast that billions of us can communicate from sending daily messages to streaming 4K videos simultaneously without interruption. To achieve this, complex networks must be built, requiring systems to organise and control their functionality. This unit looks at how contemporary systems take advantage of the ground-breaking nature of quantum technologies, which offer ultimate security for the future Internet using physical laws.

How does this unit fit into your programme of study?

This unit is mandatory for the relevant PGT programmes of study and optional on some undergraduate programmes. In all programmes of study, the unit narrates the role of both classical and quantum devices within the broader network, and readies students for an engineering future aligned to the future internet.

Your learning on this unit

An overview of content

This unit will cover the fundamentals of communications and networking systems and will include:

  • Generation of optical signals used for communication.
  • Encoding of information on to light using modulation.
  • Various modulation techniques their advantages and limitations.
  • Transmission of the optical signals and the challenges involved.
  • Types of repeaters and amplifiers and their pros and cons.
  • Detection and measurement of the transmitted optical signals as well as decoding the information using different modulation formats.
  • Methods to combine multiple signals together (i.e., different types of multiplexing) to improve throughput and create networks.
  • Elements for optical networks, fundamental technologies.
  • Types of network architecture, topologies used in modern and future networks and routing in such networks (including dynamic switching).
  • Control and management requirements and strategies for high performance networks, including network layers and control plane technologies.
  • Advantages and operation of dynamic networks.

How will students, personally, be different as a result of the unit

Students who successfully engage with this unit will learn how to design and analyse communication systems on the physical (hardware) layer and control plane. They will be aware of future developments and be able to plan for the impact of emerging disruptive technologies.

Learning Outcomes

On successful completion of the unit the student will be able to:

  1. Critically analyse and design optical communication links.
  2. Describe and explain advanced communication systems and networks including quantum communication.
  3. Analyse and discuss issues associated with optical communications and networks to address requirements of emerging and future internet applications.
  4. Design and evaluate optical networks based on knowledge of multiplexing, topologies and routing. Further, evaluate the performance and suitability of these networks for specific applications.

How you will learn

You will learn by a problem-centred approach, focusing on industry-linked problems around the current and future internet. A blend of live lectures and pre-recorded asynchronous videos will be used to cover the content of the unit. The asynchronous material will allow students on the unit to virtually visit our laboratories and testbeds, and the live lectures will build a sense of community together in solving the problems. The independent study of the regular problem sheets is accompanied by the drop-in sessions which continuous feedback and improvement for your studies.

How you will be assessed

Tasks which help you learn and prepare you for summative tasks (formative):

You will have a regular problem sheet, which will use real-world examples drawn from the lectures. There will be a mixture of the classic pen-and-paper problems to support you in developing a quantitative sense of the design of networks; wider problems which capture the qualitative role of the network engineer in the current and future internet. There will also be a research paper to read some weeks, providing guided reading to develop your knowledge of the discipline and questions that relate to this. The problems will grow in scope over the extent of the course in line with your developing knowledge and skills. Extensive formative feedback will be provided during regular optional “drop-in” sessions.

Tasks which count towards your unit mark (summative):

The unit will be assessed by a single exam in the TB2 assessment period. The exam will assess all Learning Outcomes.

When assessment does not go to plan

In the event of unsatisfactory performance in the examinations, there may be an opportunity to resit an exam of a similar nature during the reassessment period.

Resources

If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.

If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. EEMEM0002).

How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours of study to complete. Your total learning time is made up of contact time, directed learning tasks, independent learning and assessment activity.

See the University Workload statement relating to this unit for more information.

Assessment
The assessment methods listed in this unit specification are designed to enable students to demonstrate the named learning outcomes (LOs). Where a disability prevents a student from undertaking a specific method of assessment, schools will make reasonable adjustments to support a student to demonstrate the LO by an alternative method or with additional resources.

The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit. The Board considers each student's outcomes across all the units which contribute to each year's programme of study. For appropriate assessments, if you have self-certificated your absence, you will normally be required to complete it the next time it runs (for assessments at the end of TB1 and TB2 this is usually in the next re-assessment period).
The Board of Examiners will take into account any exceptional circumstances and operates within the Regulations and Code of Practice for Taught Programmes.
