Abstract


With the rapid development of computer networks and data transmission services , fiber optic communication system is toward the high-speed , high-capacity , long-distance development. Traditional EDFA with high gain and output power , but because of its band fixed and uneven gain at this stage has been unable to meet the long-distance fiber-optic communication development . Fiber Raman Amplifier online enlarged its the gain bandwidth Japanese transmission fiber characteristics , by more and more attention . It is envisaged that if both amplifiers can be mixed use , the wide bandwidth of the amplifier to get better gain flatness and better noise characteristics . In the focus of FRA on the basis of a series of theoretical analysis , the FRA and mixed amplifier design simulation and characterization results obtained capacity based on optical fiber Raman amplifiers and hybrid fiber amplifier far distance the design of the transmission system has important reference significance .
