Optical Transmission Networks

  • 150 hours
  • 4 teaching days, 3 hour tutorial, (optional) exam

Overview

This four-day course on optical systems will give you an advanced understanding of the physical layer of optical transmission systems and networks on different time, and length, scales.

The course covers all types of photonic networks, from access and metro to wide-area networks; next-generation optical modulation formats and transceivers; optical signal transmission impairments and mitigation, and optical multiplexing methods, e.g. wavelength division multiplexing, and optical and electronic network switching technologies.

It's run by UCL's Department of Electronic and Electrical Engineering.

Who this course is for

The department's short courses/CPD modules are aimed at those working in the telecommunications industry such as researchers, engineers, IT professionals and managers.

They're particularly suited to graduates in electronic and electrical engineering, communications engineering and computer science who want to further their knowledge on a particular topic, or work towards a Master's degree.

You don't need to have any pre-requisite qualifications to take this course.

Course content

During the course you'll look at the description of optical networks as a set of optical links, including the principle of wavelength routing on different time-scales (static and dynamic). This part of the course also includes optical interconnects.

On optical transmission the focus is on the elements of analysis and design of point-to-point optically amplified transmission systems as well as access applications. This covers in-depth understanding of optical transmission system design, optical amplifiers and amplified systems and the operation of wavelength division multiplexed systems.

We'll analyse both linear and nonlinear sources of transmission impairments and their accumulation with distance and interaction with dispersion.

The choice of modulation formats, fibre dispersion and electronic processing techniques are discussed with the aim of maximising the spectral efficiency, channel capacity and operating system margins.

Structure, certificates and assessment

The course runs over four days followed by a three-hour tutorial and an optional exam.

A certificate of attendance will be issued on completion for those who take the module but not the exam.

If you take and pass the exam you'll get a certificate stating this, which includes your pass level.
