High Symmetry Fiber Optic Coil for 50mm Fiber Optic Gyroscope FOG Sensor
With mass production capabilities, this φ 50 fiber optic coil combines low crosstalk and low insertion loss to provide an affordable yet high-performance solution for fiber optic gyroscopes in commercial and industrial applications.
Mainly used in closed-loop fiber optic gyroscopes with a diameter of approximately 50mm.
This model of optic fiber coil adopts a multi-pole symmetric winding method and uses 135um thin diameter optical fibers and UV-cured adhesive. The ring exhibits excellent temperature and vibration performance, and can be mass-produced with good product consistency.
