In a fiber-optic gyroscope (FOG), the quality and consistent performance of polarization-maintaining (PM) fiber coils are critical to achieving high-precision navigation. As the core sensing element of the gyroscope, the coil directly influences the system’s sensitivity, bias stability, and overall accuracy. Exail’s PM coils are expertly designed and manufactured to meet the most demanding application requirements. Each coil is tailored to specific customer specifications — from fiber type and length to winding technique and mechanical design — ensuring optimal integration and performance. Through rigorous process control and precision winding, Exail guarantees uniform optical characteristics and minimal polarization crosstalk, delivering unmatched reliability across defense, aerospace, and high-end navigation systems.
