Optical Device Current Transformer All-Fiber Freestanding Delay Fiber Coil

The current transformer all-fiber freestanding delay optical fiber coil for all-fiber current transformer customized for electric power customers meets the delay demand of FOCT. It adopts 125 / 250 μm Panda polarization-maintaining fiber and UV curing glue, and is wound with low tension, which has the characteristics of stable length and excellent all-temperature performance.

Fiber Coil Feature

1. High reliability and low cost;
2. Excellent temperature and vibration performance;
3. Full domestic supply of raw material;
4. Fast and stable batch delivery;
5. High precision;
6. Strong stability;
7. Strong anti-interference ability;
8. Small size and light weight;
9. Easy to integrate, the fiber optic gyroscope is easy to use integrated optical path technology, the signal is stable and can be directly output in digital form. This makes it easier to integrate with other devices and improves the overall performance of the system.

Application

1. Navigation field;
2. Aerospace, high-precision fiber optic gyroscope independent coils are often used for tracking and measurement of rocket launches, spacecraft stabilization, photography/mapping, attitude measurement control, etc.
