![]() These advances enable dramatic SWaP reductions in the FSO system design, making it possible to integrate high-speed laser communications to support to growing demand for data in space. Laser communications have been proposed to support to the demand for increased network capacity in space, however, conventional FSO terminals consume too much space and power to be compatible with the desired SmallSat platforms.īy leveraging recent advances in beam steering photonic technologies, CFD is developing solutions for high-speed/long-distance laser communications between SmallSats and CubeSats, including crosslinks and downlinks. SmallSats and CubeSats dramatically reduce deployment costs, enabling large constellations with the potential to collect much more data. For alternate communication channels between soldiers, drones or Tactical Operating Centers, FSO communication provides tactical advantage. Free space optical communications use laser transmission through the air to communicate wirelessly between two locations. Performance of Free Space Optical Communication Link under Foggy Weather. Uncontested LPI/LPD FSO communication provides our soldiers with secure communication without the concern of eavesdropping. The use of free space optical (FSO) technology greatly expands the available data rate in wireless communications. These assets are a consequence of the high frequency of optical waves. These include reduced mass, power, and volume of equipment, higher data rates, no tariffs and no regulatory restrictions as experienced for RF bands 6. They provide high security, low cost, low power, and high rates due to the unregulated bandwidth 1. Both RF and optical waves are electromagnetic waves however, there are many advantages to using optical waves in space. The use of free space optical (FSO) technology greatly expands the available data rate in wireless communications. F REE-SPACE optical (FSO) systems are an exciting tech- nology that establish point-to-point communication links through the atmosphere.
