2. Optical Fibres in School Physics

Comments (0)

This Association for Science Education (ASE) publication about optical fibres was developed in association with the General Electric Company (GEC). At the time of publication GEC was the largest manufacturer of electrical and electronic products in the United Kingdom, and was one of the biggest companies in the world in this field. Its products ranged from microcircuits, and optical fibres to ground stations for satellite communications, and turbine generators. It employed more than 17,000 scientists and engineers, the majority on research and development.

The booklet contained guidance for teachers and notes for students. It included activities suitable for both students aged 14 to 16 (O-level work) and for students aged 16 to 19 (A-level work).

HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
