摘要

本文分析了在由4个级联放大器组成的DWDM光系统中，EDFA自适应增益控制对80个调制c波段信道(10gbps NRZ)的影响。系统性能通过通道光信噪比(OSNR)、噪声系数(NF)、误码率(BER)和增益平坦度(GF)测量来评估。自适应EDFA方案的目标是根据这些参数的静态信息调整其设定值增益来优化NF和GF频谱，并在接收信号的BER低于FEC限制时优先考虑NF。

EDFA adaptive gain control effect analysis over an amplifier cascade in a DWDM optical system

In this paper, we analyze the EDFA adaptive gain control impact on 80 modulated C-band channels (10 Gbps NRZ) in a DWDM optical system composed of four cascaded amplifiers. System performance was evaluated in terms of channels optical signal-to-noise ratio (OSNR), noise figure (NF), bit error rate (BER), and gain flatness (GF) measurements. The adaptive EDFA scheme aims to optimize NF and GF spectra by adjusting its setpoint gain based on static information about these parameters and was improved here to prioritize NF when BER of the received signal remains under the FEC limit.
