摘要

The present paper, starting with a journey in time across the fifty years of disruptive ideas and developments available in the public literature that allowed the implementation of current free space optical communication systems by NASA and ESA, proposes the application of a CCSDS standard developed by ESA and Thales Alenia Space Italia originally developed for RF communications also for optical links. The paper mainly focuses on modulation and coding algorithms and benefits from the literature for key conclusions, based on quantum mechanics, that indicate the optical solution as more efficient and suitable for extra-long distance communications. The final goal is to highlight that, notwithstanding the existing solutions for optical modems, the CCSDS standard defined by ESA and Thales Alenia Space Italia can be used for state-of-the art optical modem developments that would also allow dual mode RF and optical operation with common and shared modem sections. Application scenarios encompass deep space communications and high speed satellite communications.
