As the demand of carrying large information in optical fiber communication network increased, there came the need of some special devices in the network to accomplish this task. For this, hybrid configurations of optical amplifiers are designed that are capable of improving the performance of the system. In this paper, a setup has been built to investigate the performance of different hybrid optical amplifiers with combination of EDFA-SOA, EDFA-RAMAN & EDFA-SOA-RAMAN with 3 channels using different bit rates of 6.25 Gbps, 12.5 Gbps and 18.75 Gbps. Performance is evaluated on the basis of quality factor, eye diagram and BER. It is observed that EDFA-SOA more suitable for RZ in comparison to other optical amplifier combination for proposed DWDM transmission link.
