FOG Components
Fiber optic gyroscope (FOG) components are the optical building blocks of a fiber optic gyroscope: the broadband light source, the multifunction integrated optical chip (MIOC), the fiber sensing coil, the photodetector receiver, and the wavelength-division multiplexing (WDM) coupler that routes light between them.
GNC Tech supplies FOG components at the subassembly level, allowing gyroscope designers to source individual optical chain elements matched to their architecture. The catalog covers five component families — MIOC chips, fiber optic coils, broadband light sources, PIN-FET receivers, and WDM couplers — with published optical and mechanical specifications per model.
Component families for fiber optic gyroscope assemblies. Each subcategory publishes full optical and mechanical specifications per catalog model.
Key Selection Parameters
Architecture Role
Identify which element of the optical chain is being sourced — source, MIOC, coil, receiver, or coupler. Each family page covers its own parameter set.
Operating Wavelength
1310 nm or 1550 nm band, consistent across source, MIOC, coil, and receiver. Mismatched wavelength components degrade gyroscope performance.
Optical Loss Budget
Sum insertion losses across all chain elements against source power to confirm adequate detected signal.
Fiber & Pigtail Compatibility
Polarization-maintaining fiber type and pigtail interfaces must match across MIOC, coil, and WDM.
Selection Workflow
- 01
Define the gyro architecture
Fix wavelength band, target grade, and closed-loop vs open-loop topology.
- 02
Select per optical element
Choose source, MIOC, coil, receiver, and coupler from the component families below, keeping wavelength and fiber type consistent.
- 03
Verify the loss budget
Check combined insertion loss against source power and detector sensitivity.
- 04
Inquire with the chain list
Send the full component list with target specifications — matching and availability are confirmed per project.
Typical Applications
- Closed-loop and open-loop fiber optic gyroscope development
- FOG-based inertial navigation and attitude reference systems
- North-finding and azimuth alignment instruments
- Optical chain prototyping and upgrade programs
Testing Considerations
- lab_profileCharacterize the assembled optical chain end-to-end, not only individual components.
- lab_profileConfirm polarization crosstalk budget across MIOC, coil, and WDM together.
- lab_profileRequest measurement conditions (temperature range, wavelength, drive conditions) for any parameter used in error budgeting.
