A Survey on Hybrid Optical Amplifiers

The optical fiber communication gains wide attraction in present time. With this communication technique, information can be sent with high data rates and low cost equipment. As there are various advantages of optical amplifier communication but its performance reduces by light dispersion effects. At the receiver end we use various types of optical amplifiers which can amplify these signals. In this paper we review that the hybrid optical amplifiers are combination of one or more amplifiers to remove the drawbacks of individual amplifiers.
