Optical fibres are highly engineered transmission lines that play a vital role in modern communications systems. i) With the aid of cross-sectional diagrams, compare step, graded index and single-mode optical fibre cables. Explain what is meant by the term 'critical angle' in this context. ii) Explain why a single-mode fibre-optic cable is better suited to the transmission of data over a significant distance. What is its disadvantage?
