FOG Fiber Coil

Polarization-maintaining fiber Coil is the core sensitive component of fiber optic gyroscope, which is composed of polarization maintaining fiber and skeleton. The polarization-maintaining optical fiber ring adopts a four-pole/eight-pole symmetrical winding method and is filled with special sealant to form an all-solid-state optical fiber ring coil. The symmetrical winding method can effectively alleviate the influence caused by the temperature gradient and the stress gradient, and can improve the stability of the fiber optic gyroscope. The product has passed the use verification of the overall military unit, completed the development and pilot test process of the product, and has now achieved large-scale production.
