50-series FOG Optical Module
An optical component used in a closed-loop FOG is a special optical module that is composed of a fiber coil and optical devices (Y waveguide, coupler, detector, light source) fused and assembled according to the order of the gyroscope optical path. It can replace the optic fiber coil, optical devices and other loose parts for direct modular installation on the gyroscope, so as to simplify the gyroscope assembly process. Devices with 1310nm working wavelength are adopted for this module and its zero bias stability at room temperature is 0.07~0.2°/h. It has the advantages of integration, small size, and is easy to install.
