Abstract
The limitations of cascaded in-line amplifier systems using coherent modulation-demodulation schemes are discussed by evaluating the product of the data rate and the transmission distance in terms of three different aspects: linear ASE accumulation, fiber chromatic and polarization dispersion, and phase noise caused by ASE through the Kerr effect. The linear ASE accumulation is shown to make the maximum value of the data rate-distance product proportionally increase with the ratio of the amplifier output signal power to the noise figure. It is also shown that the Kerr-nonlinearity-induced phase noise limits the product of the data rate and the third power of the distance, the maximum value of which is inversely proportional to both the amplifier output signal power and the noise figure
