  15. Optical Fibre • An optical fibre consists of two parts  the core and the cladding • The core is a narrow cylindrical strand of glass and the cladding is a tubular jacket surrounding it • The core has a (slightly) higher refractive index than the cladding Therefore, total Reflection of light  ncore > ncladding
