This specialized fiber retains its optical guiding capabilities even under extreme deformations, enabling the fabrication of all fiber optic components directly on a single fiber length. This unique process involves shaping the fiber at high temperatures when quartz glass becomes ductile, resulting in a spliceless, highly integrated system.

The new FOG IMUs inherit the best physical and performance characteristics from Fizoptika Malta’s renowned single-axis FOGs. The spliceless design, when all optical components are fabricated on a single fiber length, ensures seamless integration with zero optical loss. This translates to remarkably low-noise performance, reduced power consumption, and exceptional efficiency.
