Large-area fiber-optic gyroscope on a multiplexed fiber network.
We describe a fiber-optic gyroscope based on the Sagnac effect, realized on a multiplexed telecom fiber network. Our loop encloses an area of 20 km² and coexists with Internet data traffic. This Sagnac interferometer is capable of detecting signals that are larger than 10(-8) (rad/s)/√Hz, thus approaching ring laser gyroscopes without using a narrow-linewidth laser or sophisticated optics. The ...
متن کامل2000a Fiber Optic Strain Measurement System
The Fibera 2000A Fiber Optic Monitoring System is a system that identifies defects occurred in a structure that can not be easily detected from its surface. The integrity of structures such as building, nuclear reactor, power plant, rapid transit system, oil pipe, aircraft, and bridge, etc. that are vitally important to our lives, can be closely monitored and issue warnings if a defect is occur...
متن کاملPON-Based All Fiber-Optic Access System
Yoshio Miyamori Yoshihiro Ashi Eisuke Sato Mitsuhiro Takano ABSTRACT: Deployment of optical fibers in the access network is expected to have a large impact on the realization of multimedia services such as video on demand and home shopping. The passive optical network (PON) method allows for implementation of the Fiber to the Home (FTTH) service at low cost, due to sharing of the optical transm...
متن کاملSwitchable fiber optic laser system for high and low-strain fiber optic sensors remote multiplexing
In this paper, a 50 Km remote and switchable fiber optic sensing system based on an erbium doped fiber ring laser is proposed. The system allows the integration of different interrogation methods based on the detection of wavelength or amplitude variations of the laser. This integration is carried out by sequentially activating different ring cavities by using an optical switch. With this schem...
متن کاملAn Adaptive Damping Network Designed for Strapdown Fiber Optic Gyrocompass System for Ships
The strapdown fiber optic gyrocompass (strapdown FOGC) system for ships primarily works on external horizontal damping and undamping statuses. When there are large sea condition changes, the system will switch frequently between the external horizontal damping status and the undamping status. This means that the system is always in an adjustment status and influences the dynamic accuracy of the...
