FBG Optical Bragg Gratting Sensors

Being a fiber optic sensor, a chirped fbg sensor has all the advantages usually attributed to these devices, such as low loss relative to the fiber length, immunity to electromagnetic and radio frequency interference, small size and weight, intrinsically safe operation in environments characterized by hazardous materials, high sensitivity and long-term reliability.

FBG STRAIN SENSOR

FBG Strain Sensor measures the strain by utilizing the inherent feature of strain sensitivity of FBG. The kind of FBG sensor fits to be embedded to measure the strain in a ban, bridge, tunnel, and other constructions.

FBG TEMPERATURE SENSOR

FBG Temperature Sensor measures the temperature by utilizing the inherent feature of heat sensitivity of FBG. All the capsulation is specially designed to make the measurement free from the influence of pressure, strain, etc. T&S provides high-quality FBG optical sensors at a reasonable price.

Fiber Optic ID Reflector

FBG ID reflector independently developed and patented by T&S has built-in fiber Bragg grating, and has the shape of SC / LC attenuator, which is convenient for fiber docking. FBG ID reflector is installed at the end of the optical fiber near the ONU. Through OTDR detection of its reflected signal, the fiber breakage, abnormal loss and fault location can be accurately grasped, and the fault location can be spotted quickly.

FBG ID REFLECTOR

FBG ID Reflector can be used in FTTX fiber trouble-shooting monitoring. The combination of the OTDR and FBG Reflector can detect and locate fiber faults in minutes, protect the investment of unused fibers, and reduce the cost of maintenance.

Fiber Bragg Grating Technology

Fiber Bragg gratings are made by laterally exposing the core of a single-mode fiber to a periodic, intense laser mode. Exposure causes the refractive index to permanently increase in the core of the fiber, generating a fixed exponential modulation according to the exposure mode. This fixed exponential modulation is called grating.

During each periodic change in refraction, a small amount of light is reflected. When the grating is periodic, all the reflected light signals form a large reflection at a particular wavelength. This is called the Bragg condition, and the wavelength at which this reflection occurs is called the Bragg wavelength. The length of the phase mismatch is essentially transparent except for the Bragg wavelength of the optical signal at the wavelength.
