A step-index Fiber has a core index of refraction = 1:25. The cut-off angle for light entering the Fiber from air is found to be 8.50º.- (1) What is the numerical aperture of the Fiber? (2) If the Fiber were submersed in water witi same NA, what would be the cut-off angle when nwater = 1.33. (3) Find the power of the Fiber after (2) km, when te power losses is (1.5) dB/km.
