What equipment is used to help minimise the effect of signal degradation in long runs of fibre optic cable?

• Repeaters

• Amplifiers

• Hubs

• Switches

Fibre optic cables can be used to transmit data over distances as far as ​ (a)   miles

• 2000
• 5
• 150
• 500

A disadvantage of fibre optic repeaters is;

• Decreased complexity

• Reduction in cost

• Reduced latency
• Increased latency

Fibre optics are employed in fields including

• Engineering

• Medical

• Automotive

• Plumbing

• All of these

Fibre optics uses light to transmit​ ​ (a)   over long distances​
