Security Enhancement in WDM PON by Using Broadband Light Source (BLS)

Optical Network plays a important Role in Communication. WDM PON is the one of the most promising technique used. As its provides higher bandwidth to the Users, Higher Speed, Reliable communication and higher Security. In order to increase more Security, attempts are proposed to increase the physical security in wavelength Division multiplexing (WDM PON). A 16x10Gbps WDM PON system is proposed. Security enhancement is done by the use of Broadband Light Source (BLS) in the Optical Line Terminal (OLT). So, that each data frame is transmitted in unique wavelength. Through the Simulations proposed architecture of WDM PON is successfully evaluated.
