Space Optical Links for Communication Networks

  title={Space Optical Links for Communication Networks},
  author={Alberto Carrasco-Casado and Ramon Mata-Calvo},
Future spacecraft will require a paradigm shift in the way the information is transmitted due to the continuous increase in the amount of data requiring space links. Current radiofrequency-based communication systems impose a bottleneck in the volume of data that can be transmitted back to Earth due to technological as well as regulatory reasons. Free-space optical communication has finally emerged as a key technology for solving the increasing bandwidth limitations for space communication…
