Sensing FBG / FBG Array

Fiber Bragg Grating (FBG) is a diffraction grating formed by periodically modulating the refractive index of the fiber core. It is a passive filter element, and has been widely used in the production of fiber lasers, fiber optic communications and sensing. At T&S, we have FBG wavelength locker, chirped FBG, sensing FBG and sensing FBG array at sale.
FBG Array is a optical passive component. Multiple FBGs are inscribed on the same fiber FBG array, which is suitable for long-distance and multi-point simultaneous testing. FBG array can improve the stability and reliability of the system, widely used in fiber optic sensing systems. Sensor packaged with FBG array is smaller in size and has more measurement points, and it is widely used in the measurement of electric power and aviation applications.

FBG Sensors

FBG sensor based on fiber Bragg grating technology has special advantages. The most important thing is that the sensing signal is wavelength modulated and has strong multiplexing ability. Measurement signal is not affected by fiber bending loss, link loss, light source fluctuation and the influence of factors such as the aging of the detector. Moreover, optical fiber sensors present undeniable advantages such as high fatigue limits, multiplexing and immunity to electromagnetic interferences. When multiple sensing FBGs are connected on a single fiber and the sensors are embedded to the structure, several parameters can be monitored at the same, hence realized a quasi-distributed sensing system.
T&S’ FBG Sensors have been widely used in spacecraft and ship, civil engineering structures, power industry, petrochemical Industry, medical and chemical sensing, and telecommunication engineering etc. With our variety of high quality FBG sensors you are able to measure an array of parame

FBG ID Reflector

FBG sensors are easy to install, electromagnetically safe and can also be used in highly explosive atmospheres, but having the right interrogator in place is also important to retrieve the most accurate measurements.
FBG Interrogators are high-precision measuring instruments for signal obtaining and processing from FBG sensors under operating conditions. Suitable for large scale sensing networks, T&S’ FBG interrogators (TS-WI) controls up to 24 channels (4 channels on TS-WI-HS) and provide precise and high resolution measurements through reliable software interfaces and remotely read all connected sensors in real time.

FBG Interrogator

Generally, FBG ID reflector is of standard SC/LC type connector structure, in which a special FBG is encapsulated in a ceramic ferrule. At T&S, the reflector can also be SC pigtail structure or stainless steel tube package type. The FBG ID reflector is a low-cost specific band reflector mounted on the optical network unit (ONU) side. It reflects light pulses from the OTDR on the fiber line terminal (OLT) side nearly 100%, while the working bands of the passive optical network (PON) are transmitted normally.
The OTDR determines whether the fiber is normal by detecting the signal reflected by the reflector. When the reflected signal is lower than the normal value, the line loss is considered too large; when the reflection value is almost zero, then the fiber line is broken.
