Designing of Novel Security Based WDM-Pon System by Using Broadband Light Source (Bls)

Abstract

The Optical network plays an important role in the communication field because of its inherent benefits. It reduces capital and operational cost and also supports a wide range of new and high-bandwidth applications. The most effective and promising technique used in the Optical communication is WDM-PON (Wavelength division multiplexing passive optical network). WDM-PON provides relatively higher bandwidth security, high speed and makes communication reliable but security is the main issue on which various attempts are made to increase this security level in WDM-PON. In this paper, a 20 X 10 Gbps self-protected WDM-PON architecture is used to enhance the security level by using the Broadband light source (BLS). The results of this study show that physical security can be achieved through Broadband light source in which each frame is transmitted at a unique wavelength and secured data is obtained at the output. The Performance analysis is performed by using the Optisystem software.
