Description

电控光纤衰减器

电控光纤衰减器(EVOA)采用基于MEMs技术的可调光衰减器,通过调整内部的MEMS反射镜角度可以调节输入和输出光纤之间的衰减系数,它即可以用于控制单模光纤的光功率,也可以工作在输出光功率锁定模式下。衰减量大于25 dB,通过面板电位器手动旋转或SMA接头施加外部控制电压(最大频率1 kHz),可以连续调谐 衰减。输出功率以mW为单位显示在前面板上。显示的输出光功率默认状态在1550 nm校准,也可以在EVOA工作波长范围内进行其它波长的自定义校准。特有的功率锁定功能,能够自动稳定地输出功率。只需将EVOA调节到所需的功率水平,并按下锁定按钮即可,在这种模式非常适合校正长期测量中出现的慢速漂移。
