Question: Suppose that the optical fiber of Example is submerged in water (with n = 1.33) instead of air. Determine θa and fpin that case.
Example: Transmission Data Rate on Optical Fibers A 1 km long optical fiber (in air) is made of a fiber core with an index of refraction of 1.52 and a cladding with an index of refraction of 1.49. Determine
(a) the acceptance angle θa, and
(b) the maximum usable data rate of signals that can be transmitted through the fiber.
