Observation

Most candidates are well-informed and have a good understanding of the subject matter. They were knowledgeable about the differences between optical fibre and fibre optics. They were able to provide valid reasons why optical fibres are often preferred over copper cables in telecommunication.
           EXPECTED RESPONSES:
                    (a)        Fibre optics
Technology that transmits information/data using pulses of light (through thin transparent fibres made of high-quality glass/plastic).                                                 

            (b)        Reasons for preferring optical fibres to copper cables

• Have greater bandwidth
• Transmits signals faster
• Cover longer distances
• Greater efficiency
• High-quality transmission
• Low resistance
