>在线式光纤消偏器（In-line Fiber Depolarizer）的核心作用是消除光信号中的偏振态依赖性，将输入的偏振光转化为非偏振光，从而抑制偏振波动引起的系统噪声、漂移与增益不稳定性>>。它通过全光纤集成结构实现高稳定性、低损耗的消偏效果，是高精度光学系统中不可或缺的关键元件，广泛应用于高稳定性光纤通信、传感与激光系统中。

>*>规格为不带连接器，上述规格参数在中心波长、无连接器、室温23℃条件下测试得出。
>*>规格为不带连接器，对于带连接器的器件，插入损耗（IL）将增加0.3dB，回波损耗（RL）将降低5dB, >慢轴默认与连接器Key键对齐。
>*>对于不同功率参数，产品采用封装尺寸不同。
