Fibre Optic Communications

zoom

An increasingly utilised technology, fibre optics are an important medium used in modern communication systems. This Experiment Card allows the learner to explore how fibre optic cables are used to transmit signals in communication devices and systems.

Typical topic areas include:

• Optical Fibres
• Light in Optical Fibres
• Optical and Electrical Characteristics
• Analogue Communication via Optical Fibres
• Digital Communication via Optical Fibres
• Digital Communication of Analogue Signals
• Fibre Optic Troubleshooting

Typical activities include: 

• Demonstrate a simple fibre optic communication system.
• Recognise how an optic fibre transmits light by total internal reflection.
• Describe how an optic fibre is constructed.
• Describe the optical characteristics of a fibre optic cable.
• Determine the electronic transmission characteristics of an optical fibre link.
• Demonstrate a simple fibre optic communication system.
• Outline the problems with analogue optical communication systems.
• Demonstrate a simple digital fiber optic communication system.
• Recognise the extent of digital optical communication systems.
• Demonstrate the transmission of an analog signal using pulse width modulation.
• Demonstrate the transmission of an analogue signal using pulse position modulation.
• Troubleshoot a fibre optic system.
