Abstract
In this paper a theory is advanced to describe power and SNR approaches to end-to-end gain equalization for a chain of erbium-doped fiber amplifiers (EDFAs). Closed-form expressions are provided which relate the maximum allowed number of amplifiers to the major system parameters and individual amplifier performance. We are able to directly compare the maximum transmission distance allowed by power and SNR equalization schemes. Results indicate a potential 3-7 fold increase in transmission distance achieved with power equalization relative to SNR equalization. The relative merit of the former scheme is dependent upon the individual amplifier gain imbalance and the number of channels.
