Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber adjustment, in particular to an all-optical online mini squeezed optical fiber polarization controller. Background Art

[0002] The all-fiber in-line mini squeeze fiber polarization controller is a device used to control the polarization state and transmission direction of light. When the all-fiber in-line mini squeeze fiber polarization controller drives the optical fiber to rotate, the direction of the polarization axis inside the optical fiber will change, which will cause different effects on the optical signal when it propagates in the optical fiber. Specifically, rotating the optical fiber can change the polarization direction of the optical signal, thereby achieving precise adjustment of the polarization state of light;

[0003] During the use of the existing all-fiber online mini squeeze fiber polarization controller, the optical fiber is usually placed in the placement slot, and then the optical fiber is limited by a pressure plate to prevent the adjustment effect from being affected by the displacement of the position of the optical fiber during the adjustment process. After the optical fiber is limited and fixed by a fixing device, the operator uses a knob to drive the fixing device to rotate, and the fixing device drives the optical fiber to rotate, thereby adjusting the polarization state and transmission direction of the light;

[0004] During the use of the existing all-fiber online mini squeezed fiber polarization controller, although the operator can manually rotate the position of the optical fiber, this method has a large adjustment range and relatively low accuracy. Some all-fiber online mini squeezed fiber polarization controllers use an adjusting device to drive the fixed device to rotate, and then adjust the position of the optical fiber. Although this method improves the accuracy, after adjusting the position of the optical fiber, it is often necessary to set an additional self-locking component to lock and fix the optical fiber. The operation is cumbersome and reduces work efficiency. For this reason, we propose an all-fiber online mini squeezed fiber polarization controller. Utility Model Content
