Abstract
Abstract
Nowadays, the optical fiber communication system has great importance in the communication area. Although the optical fiber communication system has many favorable circumstances, the dispersion was considered one of the main problems. In this paper, the comparison between the design and simulation of different dispersion compensation schemes was displayed. There are different kinds of optical fiber dispersion compensation systems such as fiber Bragg grating (FBG) and dispersion compensation fiber (DCF) are extensively used for optical communication systems. They are usually considered imperative techniques to compensate for the dispersion. The simulation results have been analyzed depending on various parameters by utilizing advanced Opti-System software. The best performance of the system is when the bit error rate (BER) reaches to 1.7 × 10−12 at 1550 nm wavelength and the Q-factor is 6.9 at the 0.000195 eye opening. The modal was simulated using the appropriate parameters which include CW laser wavelength, fiber length (km), and attenuation coefficient (dB/km) at the transmitter side. Three various parameters were tested such as BER, Q factor, and eye-opening.
