In today’s technology, optical fibers are becoming more and more fundamental to basic transmission media in the communication world. Optical system is to improve the quality factor and use to optimize noise reduction. This paper presents the idea of improving Quality Factor (QF) and noise reduction in a Passive Optical Network (PON) network by building a Wavelength Division Multiplexing (WDM) system and implements the Dense Wavelength Division Multiplexing (DWDM) network with Fiber Bragg Grating (FBG). A laser beam is used as source. The input is allocated to 16 channels at different wavelength. For modulation, Phase Modulation (PM) technique is used. The modulated signal is transmitted to the destination through a Single Mode Fiber (SMF).The distance between the source and destination is 50km. The signal is amplified using Erbium Doped Fiber Amplifier (EDFA). The amplified signal is forwarded to demultiplexer. 16 FBG are placed in de-multiplexer subsystem. The FBG reflects a particular signal and transmits it to the photo detector. The refracted signals from the FBG will be forwarded to other FBGs. The signals from the photo detector is analyzed for various parameters like Bit Error Rate (BER), Quality factor and eye diagram. The simulation software used in this paper is Optisystem version 7.0.
