To combine the benefits and compensate for the drawbacks of different optical amplifier types, a hybrid amplifier can be composed. The authors consider two most frequently used hybrid amplifiers that can provide better performance: a semiconductor optical amplifier (SOA), and an erbium doped fiber amplifier (EDFA), both in combination with a distributed Raman amplifier (DRA). To compare performance of the hybrid amplifiers, the eye diagrams of detected signals were analyzed and the maximum transmission distances were found. The results obtained show that even under the conditions advantageous for a SOA-DRA hybrid, the EDFA-DRA combination will produce less distortions of the amplified signal.
