Abstract

We carried out simulative analysis to investigate the spectral efficiency of 8 X 112 Gb/s wavelength-division-multiplexed systems based on polarization-multiplexed 16 quadrature amplitude modulation format along with coherent detection and digital signal processing. We employed SSMF fiber as a channel with pure EDFA amplification. The WDM system was analyzed and compared by measuring performance parameters with channel spacing 100 GHz,75 GHz, 50 GHz and 25 GHz at a fixed length of 100 km at 0 dB power level.
