Performance Control of Semiconductor Optical Amplifier and Fiber Raman Amplifier in Communication System

Optical fiber communication greatly develops considering the limitations of communication systems corresponding to the demand of information needs. Optical fiber is one of waveguides that is able to transmit information with large capacity, high speed and low attenuation. Due to the very long distance, then the signal transmission needs to be maintained from the disturbance of geometry, materials and signal sources. To maintain the signal, optical amplifier is required although several amplifiers still have problems. This paper investigates the performance of Semiconductor Optical Amplifier (SOA) and Fiber Raman Amplifier (FRA). Using the simulation application, both amplifiers are designed and compared by inline amplifiers. The results showed that the transmission distance of FRA is more stable than SOA. However, this FRA system has higher power consumption when compared to the SOA system.
