Abstract
In this paper, a single-channel optical communication system is optimized to achieve the maximum possible range of communication. Then it found increment in transmission distance with a single point use of EDFA. Since EDFA depends upon various parameters such as the length of EDFA, the concentration of erbium atomic fiber, the type of pump configuration, the wavelength and power of pump signal and the input signal. The EDFA parameters used are first optimized to obtain a reasonable flat gain. Then optimized EDFA parameters after the parametric analysis are used in a single-channel optical fiber communication system. Maintaining the BER lesser than 10−9 (i.e., the maximum BER that can be considered in digital communication), it compared the transmission distance for single-channel communication system without and with EDFA. Further, it has also investigated an 8-channel WDM system in which the optimized EDFA is used as a repeater/amplifier. The obtained output signal power, BER through eye diagram, ensure our results. This shows EDFA helped significantly in increasing the transmission distance along with providing minimum BER and maximum output signal power. These simulations and analysis are performed using Opti-System15 simulation tool.
