We’re thrilled to announce our involvement with IRIS² (Infrastructure for Resilience, Interconnectivity, and Security by Satellite), the European Commission’s ambitious initiative to deploy a constellation of 290 satellites aimed at boosting secure communications and surveillance capabilities across Europe. This cutting-edge network will also extend broadband access to the public and various industries.
Our team recently participated in key discussions about how Fiber Optical Solution can contribute to this massive €10.6 billion project. Being a part of IRIS² not only aligns with our commitment to innovation but also positions us at the forefront of Europe’s expanding space technology landscape.
We’re excited about the future and eager to see how our participation will drive technological advancements and new opportunities.

We are excited to announce the publication of our collaborative research paper with Exalos. This joint effort marks a significant milestone in the development of cutting-edge inertial measurement units (IMUs) and highlights the innovative advancements achieved by the partnership between Fiber Optical Solution and Exalos.
The paper, titled “High-Precision Inertial Measurement Unit with Closed-Loop Fiber Optic Gyros – operated by a new 1550nm 3-fiber SLED transceiver” details a revolutionary approach to IMU design.
Key achievements include:
The new IMUs are based on 3-axis closed-loop fiber optic gyroscopes (FOGs), leveraging a highly integrated optical transceiver that includes a 1:3 beam divider, a 3-channel optical circulator, and integrated receiver photodiodes.
This breakthrough not only enhances the performance and reliability of IMUs but also demonstrates the potential of collaborative innovation in fiber optic technologies.
The full paper is available at IEEE Xplore.
We are proud to contribute to advancements in the field of inertial measurement systems and look forward to exploring further collaborations with Exalos and other industry leaders.
In a joint presentation by EXALOS and FIBER OPTICAL SOLUTIONS (FOS) at the 61th DGON ISA symposium, experts from both companies demonstrated a novel integrated 1550 nm 3-fiber SLED transceiver module and its application in a high-precision Inertial Measurement Unit (IMU) for navigation.
The symposium took place in Brunswick (Braunschweig), Germany at October 22-23, 2024, as a face-to-face event.
The advanced 14-pin Butterfly (BTF) module is realized with a micro-optical, free-space bench technology.
The broadband SLED emits an optical spectrum with 3dB bandwidth of 33 nm around a center wavelength of 1549 nm. The output is collimated into three output beams that are propagating through an optical circulator before being focused into an array of three PM output fibers. Efficient beam collimation and low-loss beam propagation on the optical bench in combination with high-efficiency coupling to the PM output fibers results in output power values of around 1.0 mW per fiber channel at low drive currents of only 150 mA.
Higher output power values are obtained at higher SLED drive currents. The polarization extinction ratio (PER) of each fiber port provides more than 15 dB.
Three integrated receiver photodiodes detect the returned light from the PM fiber loop of the corresponding FOG. The design provides low transmission loss as well as high isolation and, therefore, high wavelength and power stability against backward-propagating light.
All in all, the low-loss optical architecture in forward and backward direction offers power-efficient operation with low SLED drive currents and thus low TEC currents over the full temperature range from -40°C to +85°C.
The original, popular IMU required a wide range of discrete optical components, including depolarizers, fiber splitters or fiber-pigtailed photodiodes, as well as eleven splices of polarization-maintaining (PM) fibers.
The new innovative IMU design is based on the new integrated EXALOS SLED transceiver module. The 14-pin Butterfly (BTF) module delivers broadband light with similar optical power levels and with a high polarization extinction ratio (PER) at three PM output fibers.
This allows the direct splicing to the three phase modulators (MIOC), reducing the number of PM fiber splices to only three:
Thanks to the micro-optical integration of the three closed-loop FOGs in the 14-pin BTF module the number of external components and finally the IMU footprint is significantly reduced.The joint presentation, which was received with great interest, took place on Wednesday, 23-Oct-24.
Both companies looking forward to further successful cooperation in the development of innovative, market-leading products.
