Abstract

Optical amplifier has been an essential component in long haul optic system in transmission system. In order to enhance the capacity of an optical system, the optimization of the signal parameters and system components is a critical task. In the real system, there are many parameters that can be adjusted to achieve the desired performance levels. However, this requires implementation of time–consuming procedures. This project simulates WDM system design in order to optimizing the pump powers of a Raman Fiber Amplifier for a target gain and best gain flatness using OptiSys 7.0 software. Many parameters related Raman Amplifier such as length of amplifier, wavelength of pump power and input pump power have been optimized in order to obtain Noise Figure (NF), Optical Signal Noise Ratio (OSNR), gain, Bit Error Rate (BER) and Q Factor performances. These parameters were varied from a certain range of pump power 500mW to 1W, length of amplifier 23 km to 25 km and wavelength 1450nm to 1460nm and results viewed using Dual Port WDM Analyzer and BER Analyzer.
