　　为了根据外界条件的变化自动进行增益调整，引入了中间级接入掺铒光纤放大器，它具有两级放大功能，增益在一定范围内可调，且能自动根据系统的变化调整自身的增益，使其满足不同条件的应用需求。采用自动增益校准的方法，对其原理进行了理论分析和实验验证，取得了中间级接入掺铒光纤放大器的增益校准及验证数据。结果表明，自动增益校准数据具有较高的准确性。这一结果对掺铒光纤放大器实现快速、准确的自动增益控制是有帮助的。

In order to adjust the gain automatically under different environmental conditions , an erbium-doped fiber amplifier (EDFA) with mid-stage access was introduced , which had two amplifier stages and variable gain within a certain range.To achieve the purpose of automatic gain adjustment , the method of automatic gain calibration was adopted .After theoretical analysis and experimental verification , the data of gain calibration and verification of the EDFA with mid-stage access were obtained.The results show that the data of automatic calibration has high accuracy .This research is helpful for EDFA to achieve automatic gain control rapidly and exactly .
