components of some computers communicate with each other through optical fibers

Question

components of some computers communicate with each other through optical fibers having an index of refraction n = 1.55. What time in nanoseconds is required for a signal to travel 0.19 m through such a fiber? components of some computers communicate with each other through optical fibers having an index of refraction n = 1.55.

What time in nanoseconds is required for a signal to travel 0.19 m through such a fiber?

Explanation / Answer

Solution:

Velocity of light inside optical fibre (v) = speed of light / refractive index

=> v = 3 x 10^8 / 1.55

=> v = 1.935 x 10^8 m/s

time taken = distance / velocity

=> 0.19 / (1.935 x 10^8)

=> 0.98 ns

Time taken = 0.98 ns
