OPTICAL FIBER COMMUNICATION SYSTEM PROF. A.M.ALLAM 1-A LED of radius 20 um puts out 0.2 mW. How much power is coupled in 50/125 SI fiber whose NA=0.25. Repeat for the single mode SI fiber of 5/125 with NA = 0.15 2-A LED of radius 25 um is coupled to 5 um SM fiber with numerical aperture 0.15 . Determine the coupling efficiency. 3-A laser of dimensions 0.5x0.5 um2 puts power 0.2 mw. How much power is coupled to a SM fiber with numerical aperture 0.15 and radius 5um. 4-The mean optical power launched into an optical fiber link is 1.5 mW and the fiber has an attenuation of 0.5 dB/km. Determine the maximum possible link length without repeaters (assuming lossless connectors) when the minimum mean optical power level required at the detector is 2 μW.
