FOG1500 is one device designed with the best performance of the dynamic range;up to 1500deg/sec Operating at the wavelength of 1550nm,this waveband the light transmiss with the lowest insertion loss.The gyro ASE light source has a high output power together with the good wavelegth stability.This state-of-the-art closed loop fiber optic gyroscope (FOG) designed and developed entirely in-house.The FOGPhotonics delivers superior precision and reliable performance at lower cost and smaller size than other comparable gyros, especially other FOGs.
