Feasa produces a range of Couplers Manufactured from high Numerical Aperture (NA) 80 micron fiber. High NA fiber has low bend attenuation compared to standard singlemode fiber. It has application anywhere the fiber needs to be tightly coiled or is subject to sharp bends or twists. It is suitable for Fiber Optic Gyroscope (FOG) Couplers. For different systems many coupler types are available.
