#1: An optical fiber has a core refractive index of 1.48 and cladding refractive index of 1.46. Pico-second light pulses propagate through a 5 km long fiber. (a) Find the time (to) it will take for a ray of light to travel along the axis of the fiber. (b) Find the pulse width after the pulses travel through 5 km fiber. (c) Estimate the maximum bit-rate at which data can be sent over such a fiber.
