DQuestion 8 10 pts An 11 km long graded-index multimode fibre has an optical bandwidth distance product of 2.1 GHz.km. What is the total fibre dispersion per kilometre for the multimode fibre? 178.6 ps/kon 893.6 ps/km 209.5 ps/rn 980.75 ps/km 8.11 ps/km 81.85 ps/km D Question 9 10 pts A fibre has a total rms pulse broadening of 3.5 ns. The laser and photodetector connected to either end of the fibre have bandwidths of 150 MHz and 1.6 GHz respectively. What is the maximum recommended digital transmission rate for a non- return to zero data source connected to this optical fibre system? Rsm 150 Mb/sec Rma100 Mb/seo Rijmaz 156.3 Mb/sec RMas166.3 Mb/sec Repmar -800 Mb/see Ras 37.8 Mb/sec DQuestion 10 10 pts A 5 km optical fibre link consisting of graded-index fibre has a multimode delay difference of 0.61 ns. The fibre has a relative refractive index difference of 0.7%. What is the core axis refractive index? c1.461 neo n1.476 no, = 0.001
