7. A fiber hаs аttenuаtiоn оf 0.00004 dB/m. What is the tоtal attenuation of a 100 km length? 8. Determine the length of an instantaneous pulse sent through a 50 km multimode fiber with a total dispersion of 3.75 ns/km. 9. You lose 0.5 dB coupling a 1067 nW HeNe laser into a multimode optical fiber. Another 0.15 dB loss occurs at the receiving end. Determine the length of the fiber, knowing that the output signal is 0.49 µW. (Attenuation is 0.01 dB/km) 10. a) Determine the total chromatic dispersion for a fiber with a waveguide dispersion of 7.5 ps/nm-km and a material dispersion of 16 ps/nm-km. b) This fiber is used in a communication system for transmitting 125 ps pulses by using as a source a HeNe laser (632.8 nm) with a spectral width of 0.015 nm. Determine the width of the output pulse knowing that the fiber length is 75 km. 11. An instant pulse is sent through a step index multimode fiber with a length of 50 km. The fiber has a characteristic dispersion of 9.5 ns/1000m. Determine: a) The modal dispersion of the fiber. b) The data rate (Data rate = 0.7/pulse spreading).
