Study of Dispersion Compensation with Dispersion Compensating Fiber in 10 Gbps Single-Mode Fiber

Abstract

The industrial revolution was able to solve various social challenges in society, which create a sustainable life and bring people to the uttermost advanced society, Society 5.0. In Society 5.0, a massive amount of data from the sensor will rapidly accumulate in cloud services. It requires enormous bandwidth and high-speed communication than can be achieved by using optical fiber as a transmission media. However, chromatic dispersion will limit the bandwidth and data rate due to pulse broadening, which needs compensation. Among many compensation techniques for optical fiber systems, this research investigates the effects of dispersion compensating fiber (DCF) in a single-mode-fiber (SMF) using a 10 Gbps bit rate at various source power levels. This research considers three different schemes of DCF, i.e., pre-compensation, post-compensation, and symmetrical compensation with NRZ modulation format at transmission distances up to 200 km simulated by using OptiSystem. The results show that the dispersion effect can be compensated by the proposed DCF scheme. Also, the use of amplifiers should be considered to compensate for the high attenuation effect of DCF. The system performance showed that using a three different scheme of DCF could provide a good system performance and reach a transmission distance of 200 km.
