. A multimode fiber has RMS pulse broadening per km of 12ns/km and 28ns/km due to material dispersion and intermodal dispersion resp. Find the total RMS pulse broadening.

Question

Quizplus · Accepted Answer

The total RMS pulse broadening in a multimode fiber is found by taking the square root of the sum of the squares of the individual broadening effects (due to material dispersion and intermodal dispersion). Thus, total RMS pulse broadening = sqrt((12^2) + (28^2)) = sqrt(144 + 784) = sqrt(928) = 30.46 ns/km.
