摘要：

In the last few decades, optical technology has become much advance to transmit higher traffic over a long distance. In spite of this, physical layer impairments (PLIs) poses a great concern over the optical communication to meet the demand of next generation technology. Hence, PLI aware algorithm is a major factor to improve the quality of an optical network. This paper discuss the quality estimation based on optical signal-to-noise ratio (OSNR). This approach includes noise due to amplifier spontaneous emission (ASE) in optical fiber, multiplexer, demultiplexer, and coherent crosstalk in optical switches to present OSNR in a wavelength division multiplexing/dense wavelength division multiplexing (WDM/DWDM) networks. In this work, estimation of ASE noise power for different values of wavelength and bandwidth has been discussed. This paper also presents a routing and wavelength assignment (RWA) algorithm based on OSNR to improve the quality of transmission.
