Optical Sensor Interrogator for Fiber Bragg Gratings
The NI PXIe-4844 optical sensor interrogator is a dual-slot 3U PXI Express data acquisition module for fiber Bragg grating (FBG) optical sensors. It has four optical channels that are simultaneously sampled at 10 Hz for measurement of FBG strain and temperature sensors.

Because FC/APC connectors are male, female to female bulkhead adapters are necessary to connect FC/APC optical sensor arrays to the FC/APC to LC/APC adapter cables.
You need FC/APC to LC/APC adapter cables to connect FC/APC optical sensor arrays to your optical sensor interrogator. Leaving the adapter cables on the instrument helps prevent wear and contamination of the interrogator's optical connectors.
The chassis provides rugged, modular housing for the controller and modules and contains the high-performance PXI backplane, which includes the system's data, timing, and triggering buses.
The controller runs your application and interfaces with your PXI modules.
You need software to interface with your hardware and to collect, analyze, present, and store your measurements. This board is compatible with a variety of programming languages, including LabVIEW, C/C++, Visual Basic, and .NET. LabVIEW provides the easiest integration with all of your NI hardware and is recommended to maximize your hardware investment.
