3.3.2 - Refraction, Diffraction & Interference with 100% Correct Answers

Test Bank Solution Manual for Optical Fibres & Refraction + Waves and Diffraction Explain how the glass cladding around the optical fibre's core improves the security of data being transmitted through it give a reason why this is important. - Answers *light does not enter the cladding so cannot pass across from one fibre to a neighbouring fibre* (1) fibres without cladding can allow light to pass between fibres when the surface of the fibre becomes scratched (1) personal data (...
