dc.description.abstract In order to deliver high data rate (content/applications) over the optical networks, higher order modulation schemes play a key role along with effective coding techniques. Quadrature Amplitude Modulation (QAM) technique is believed to be one of the vastly used modulation schemes for optical communication these days. Bandwidth utilization in higher order modulation schemes is more effective as compared to other modulation schemes. Performance of 128-QAM with dual polarization for long haul optical communication has been investigated in this paper. Investigation has been carried out at data rate of 112 Gbits/s for a fiber length of 100 Km. Simulation study enables to visualize constellation diagram, optical spectrum and optical signal in time domain. Different system impairments, such as dispersion and attenuation have also been combated by the use of Dispersion Compensation Fiber (DCF) and amplifiers. en_US
