机械可调光衰减器MVOA可以让用户在光信号通过器件时手动调节光纤中信号的衰减。这些机械式VOA可以用来精确平衡光纤环路中的信号强度，或在评测测量系统的动态范围时平衡光信号

保偏光纤阵列是利用V形槽（即V槽，V-Groove)把一条保偏光纤带安装在阵列基片上。应用于保偏光波导器件、保偏准直器阵列、不同的激光源...等等！

the In-line Polarizer is designed to pass the light with the specified polarization,blocking the others.the function is tranform non-polarized light into linearly polarized light, for the high extincton ratio.It is also used to enhance the extinction ratio of the signals of precision measurement system, fiber sensor, high speed test instrumentations where the high extinction ratio prosper is required
