FOG Optical Module with 0.003°/h Precision - OM60/70/98/120 Models from Φ60mm to Φ120mm
Modular integrated sensing component combining fiber coil and MIOC for fiber optic gyroscopes. Features high precision (0.003°/h), working temperatures from -45°C to +70°C, and eliminates need for expensive PM fiber fusion splicing. Available in multiple sizes with fiber lengths from 500m to 2220m.
The FOG Optical Module is a modular integrated sensing component combining Fiber Coil and MIOC (Multifunction Integrated Optical Circuit) designed specifically for fiber optic gyroscope systems. This pre-integrated solution eliminates the need for expensive polarization-maintaining fiber fusion splicing equipment.
- Pre-spliced fiber coil and MIOC in integrated shell
- Standard electrical interface and single-mode tail fiber
- Eliminates need for PM fiber fusion splicer
- Simplifies installation and reduces system costs
