Family of modular, reconfigurable optical communication terminals spanning compact to medium form factors with 26+ space-qualified SKUs and flight-proven heritage.
The SatLight™ OCT is a family of modular, reconfigurable optical communication terminals spanning compact to medium form factors. SatLight 1 delivers 1W transmit power through a 25 mm aperture (114 dBm gain), while SatLight 2 scales to 3.2W through a 127 mm aperture (163 dBm gain) for longer-range LEO-to-GEO links.
With 26+ space-qualified SKUs and flight-proven heritage on JAXA's LEO-to-GEO optical link (3+ years operational, beacon-less acquisition in under 60 seconds), the OCT supports both SDA 2.5G and high-speed 100G/200G configurations using separate Tx/Rx beam paths.
