Title:: Four bits data sequence generators based ytterbium doped fiber amplifiers for upgrading maximum Q factor and minimum BER

Information:: Abstract: We have simulated four bits data sequence generators based ytterbium-doped fiber amplifiers for upgrading max. Q factor and min. BER. Optical power variations against time duration after fiber cable length of 250 km with the bits sequence generators of 0101, 1000, and 1010 respectively are simulated. As well as the electrical power/total received power variations against frequency after photodetector receiver with the bits sequence generators of 0101, 1000, and 1010 respectively are discussed in details. Moreover, the signal power amplitude level with the time period duration after photodetector receiver/3R regenerator with the bits sequence generators of 0101, 1000, and 1010 respectively are clarified to show the max. Q factor and min. BER values for each case.
