Abstract :
This work describes the realization of a fiber optic gyroscope with a sensitivity of 10-8 (rad/s)/√Hz. Such a high sensitivity is obtained using a 47 km long single mode fiber of the urban optical telecommunication network, that is shared with other users and encloses an area of 20 km2. This setup has been used to investigate ground motion in occurrence of earthquakes.
