In many industries and fields, the use of a Fiber Bragg Grating (FBG) Interrogator for small-scale testing is quite common. Various physical quantities are tested, such as temperature, strain, displacement, and more.Under such circumstances, the connection among the FBG interrogator, sensor, and management unit is straightforward.
As shown in the diagram, you can place the management unit and interrogator together, connect them using an Ethernet cable, and start using them. Alternatively, you can position the management unit and interrogator in different rooms under the same wireless router, as long as there is a network connection between the two, enabling direct usage.
The connection between the interrogator and sensor is even simpler. The most straightforward method is to directly plug the sensor into the channel of the FBG interrogator for usage.
However, in most cases, there might be a certain distance between the interrogator and sensor placement. Therefore, it's common to use flexible fiber jumpers and flanges to connect the sensors before integrating them into the FBG interrogator. Flexible fiber jumpers offer more convenient placement.If the distance between the interrogator and sensors is considerable, it would require specialized fiber transmission for sensor information in between.
