Effective Transmission

EDFA is an important component in WDM optical communication systems. But the uneven characteristic will lead to reduced effective transmission bandwidth and system performance degradation. This paper studies on issues of EDFA gain flattering based on long period fiber grating, and provides detailed analysis of the method of using LPFG to achieve flat EDFA output gain. Numerical simulation result shows that this method can reduce unevenness to 0.2dB and below.
