Experimental Simulation of 30×100 Gb/s DWDM Communication System

In DWDM systems data signals from different sources can share a single optical fiber while maintaining complete separation of data streams. The basic components of passive optical network (PON) are a light source, most often a laser, a receiver and an optical fiber. Article describes our topology and theory of DWDM system, the phenomena affecting the optical transmission in the 30-channel DWDM system, which was designed in the OptiSystem program. Optimization summarizes the knowledge of the systems and software that is used. The theory of RZ and NRZ modulation is described. Based on previous simulations of DWDM systems with transmission speed of 10 Gb/s and 40 Gb/s, we design a 100 Gb/s scheme, which is described in this article. We evaluate Q factor and BER parameters for these systems with changing RZ and NRZ modulation. Our goal is to improve DWDM transmission properties in our proposed system. We expect better BER parameters when deploying an EDFA amplifier over longer transport distance. An optical network with amplifiers is called an active optical network (AON).
