| Summary: | The purpose of this research is to enhance the gain signal amplification by using dual pump double pass configuration in comparative with single pump double pass that are commonly used as conventional optical amplifier configuration in optical communication system nowadays. Two input signals power have been implemented which are -30 and 0 decibel (dB). The input signal defined as low and high input signals power by using a pump power of 1480 nm. The amplification of EDFA in this study have been taken place in conventional band (C) band and long wavelength band (L) band of EDFA within the range of 1515 to 1615 nm. Therefore, to understand the performance of the gain amplification, the OptiSystem software simulator version 13 has been used for simulation and the values of fiber length and pump power has been varied for both configurations. It has been found that the, dual pump double pass configuration has shown better gain performance at lower input signal power compared to the single pump double pass configuration. |
