New Technology to Improve Space Communications
The strategic project with ESA, "Reliability of Non-Hermetic Optical Transceivers", successfully concluded after its launch in January 2021.
The project focused on evaluating a new generation of optical transceivers for space applications. Traditionally, these devices have been hermetically sealed to ensure reliability. However, commercial non-hermetic alternatives are now being tested as a way to reduce costs and enhance efficiency in space missions.
Three transceiver models underwent rigorous testing to assess their resistance to extreme conditions, such as high temperatures, vibrations, and humidity. The goal was to demonstrate that these devices can withstand the space environment without requiring costly sealing processes.
Results and Next Steps
The tests revealed that all three devices showed promising features for potential space use, although some failures were observed in specific conditions, such as exposure to humidity or temperature fluctuations.
The study suggests that these transceivers can be improved by optimizing manufacturing processes and conducting additional tests, including radiation resistance analysis. With these advancements, ALTER TECHNOLOGY and ESA continue exploring new technological solutions to enhance space communications.
