About The Provider

OpenLearn is a free learning platform, delivered by The Open University as part of its Royal Charter commitment to support the wellbeing of the community. 

Since its launch in 2006, OpenLearn has become an integrated part of The Open University, with the site attracting more than 69 million visitors – many of which go on to make an enquiry about becoming a formal student, strengthening the journey between informal and formal learning.

The OpenLearn team originate, commission and develop content that unites faculty and University priorities with areas of topical and general interest. This is in support of our own student population in their academic, skills and career and personal development (CPD) endeavours, delivering quality assets openly available for teaching and learning.


OL deliver bite-sized learning experiences designed to fit easily into daily life, so whether you're a busy parent looking to get promoted at work, or back-packing across Africa and wanting to increase your learning, we are open with no requirements to access our free materials.

Some of OL academic-led content includes:

  • 900+ short courses (ranging from 1 - 100 hours of study)
  • thousands of articles, quizzes and interactive games 
  • hundreds of videos and audios, ranging from Greek history to modern-day politics, and everything in between 
  • printed posters and booklets made for our TV & radio programmes co-produced with the BBC.

Website content covers a wide range of subjects, with many of our free courses being adapted extractions from OU modules. All of our courses enable you to earn a Statement of participation and some also allow you to earn a free digital badge. You can use your badge or statement of participation to share your achievement with others although they do not carry any formal credit towards a qualification.

Optical-fibre communications became commercially viable in the 1970s and innovation continues today. This free course, Digital communications, will illustrate how very high data rates can be transmitted over long distances through optical fibres. You will learn how these fibres are linked, examine the technology used and assess the future direction of this continually developing area of communication.
