PBT QUESTION In an experiment, a ray of light is directed towards the surface of water at an angle of incidence of 530o . If the refractive index of water is 1.33, identify: i. The angle of refraction: Formula:
ii. The velocity of light in water:
QUESTION 2 An experiment was conducted to determine acceptance angle of a fiber optic cable. The characteristics of the fiber optic cable are tabulated in Table 1 above. Based on the Table 1, a. Estimate the acceptance angle of the fiber optic cable : Value Refractive index of core 1.49 Refractive index of cladding 1.44 Numerical Aperture 0.3418
b. Identify the critical angle for the core-cladding interface:
c. Draw and lable a diagram to illustrate the acceptance angle and the reflectance angle of the fiber optic cable:
QUESTION 3 A PON (Passive Optical Network) system utilities splitter that takes one input and splits it to “broadcast” signals downstream to many users. Illustrate basic PON architecture terminated diagram with different type of Fiber to the Loop (FTTL).
