1.	What property does data transmission in fiber optic cable exploit?(a) Refraction(b) Total internal reflection(c) Diffraction(d) DispersionI had been asked this question in an interview for job.My doubt stems from Data Bus Systems topic in division Avionics System Integration of Avionics
Answer» Correct answer is (B) Total internal reflection To ELABORATE: The transmission of light signals ALONG any optical fibre depends on the optical property of total internal reflection. The transmitted light pulses get reflected by the cladding in the fiber cable at the same TIME MOVE in the forward direction. One main disadvantage of fiber optic cable is that it cannot be easily bent.
