Comparative analysis of optical amplifiers for CWDM networks

We present a cost-effective EDFA configuration for CWDM applications, using a combination of parallel and series circuits. The developed CWDM EDFA was characterized for gain and noise figure from 1490 to 1610 nm (S, C and L bands) and its performance was evaluated in terms of BER for power and line applications. The obtained results are compared to those arising from the use of a CWDM SOA under the same experimental conditions.
