QuantumX MXFS: Integrating Optical and Electrical Measurements into One Reliable System

The new QuantumX MXFS optical interrogator is a module from the QuantumX family. As it was developed from HBM FiberSensing's well-established BraggMETER technology, it is designed for precise measurement of sensors based on Fiber Bragg Gratings (FBG). At the same time, the MXFS is your integration toolkit for the reliable QuantumX data acquisition system. 
QuantumX intelligently manages your measurements and is popular for its flexibility, ease of use, modularity, and precision. By combining these two strong players, data information can be easily processed in just one system.

The setup of a highly flexible and precise measurement chain, with all the different sensors required, is simple and can be realized by “plug and measure”. The powerful catman® software can be used for data analysis of all different sensors used. 

Two operating modes can be selected by the user:

  • Normal speed mode, with 100S/s acquisition rate, most suited for monitoring projects or thermal testing of components.
  • High-speed mode, with 2000S/s acquisition rate, most suited for dynamic monitoring or experimental stress analysis.

Up to 16 Fiber Bragg Grating peaks can be connected in series to each of the 8 optical connectors - with parallel acquisition.

QuantumX MXFS thus offers an impressive 128 channels per module with simultaneous acquisition, which not only reduces the cost per measurement point but also the total cost of ownership.

Key Facts and Benefits of the MXFS

  • Used as a stand -alone device or synchronized with other QuantumX modules
  • With 8 connectors for 16 channels each totaling 128 channels per module
  • Selectable acquisition rates (2000S/s or 100S/s)
  • Compatible with the powerful catman® software but also open to other software


“With the new MXFS we are taking hybrid measurements to another level because we are combining optical and electrical technologies under the same platform, making them perfect partners,” says Cristina Barbosa, Product Manager for the Optical Business.

Part of the QuantumX family

  • Easy combination of fully synchronized signals of the Fiber Bragg Gratings with different technologies
  • Numerous combinations of the full range of QuantumX modules to best fit the application.
  • Precise and reliable data with measurement performance, active filtering, and high-level synchronization

Flexible system fitting a large variety of demands. Scalable for an even higher sensor count, ensuring a reduction of cost per measuring point and overall ownership.

BraggMETER technology

  • Wide measurement range capability with 100nm scanning wavelength range

What is an optical interrogator?

  An optical interrogator, also known as measurement unit or data acquisition system, is an optoelectronic instrument, which allows the reading of optical sensors, e.g. fiber Bragg grating (FBG) sensors, in static and dynamic monitoring applications. An FBG interrogator can measure a large sensing network composed by various types of sensors such as strain, temperature, displacement, acceleration, or tilt that connected along multiple fibers, by acquiring data simultaneously.

   During data acquisition, the interrogator measures the wavelength associated with the light reflected by the optical sensors and then converts it into engineering units. The readings are then transmitted via Ethernet or FireWire for archiving, analyzing or exporting using a software interface. With the right QuantumX modules setup, the interrogator can be integrated into different communication protocols such as PROFIBUS or CANbus.

   FBG sensors are easy to install, electromagnetically safe and can also be used in highly explosive atmospheres. In order to retrieve the most accurate measurements, you need the right interrogator. Suitable for large scale sensing networks, HBM's interrogators provide precise and high resolution static and dynamic measurements.
