In the last decade free space optical communications (FSOC), also called laser communications, has evolved from a niche to a mature technology. Recent successes have pushed this technology forward, with the aim of providing global broadband coverage.
However, FSOC still faces two major challenges to providing similar performance to terrestrial “backbone class” long-haul fiber networks, which need to be resolved in order to increase the physical link efficiency. FSOC links from Space to ground require a certain number of photons per bit in order to close the link; and some Space applications require a very large amount of data to be transferred. Using dense multiwavelength division multiplexing (DWDM) helps achieve terrabits per second data rates per link. Mynaric is at the forefront of the development of these applications and will present the state-of-the-art and an outlook into the future of FSOC. On the way to the ground, another challenge arises from the effects of atmospheric disturbances such as clouds. Therefore, robust optical communication needs to rely on a network of optical ground stations, as well as on weather forecasting in order to realize its potential.
How can terabit data rates be realized and what are the new challenges when moving from fiber to FSOC? What is necessary to ensure reliable ground to space and space to ground links through the atmosphere? In this webinar, our speakers will tackle both challenges, and show the road to bringing FSOC to the level of backbone class performance and reliability.
Carsten Fechtmann, System Architect for Mynaric’s CONDOR optical communication terminals, will present the advantages of FSOC for a directional sending and receiving of information, highlight the latest developments in very high data rate links.
Olivier Liandrat, Sky Imaging Team Leader at Reuniwatt, will outline the benefits of using reliable weather data, and present state-of-the-art cloud forecasting for OGS networks, as well as use cases from Reuniwatt’s projects.
The webinar will be chaired by Dr. Szymon Gładysz, wo will lead the audience through the webinar, and forward your questions on flexibility, security, and bandwidth of FSOC, as well as transmission through clouds to the panelists.
