Terabit Free-Space Demo

Partner: DLR

In 2016, 1.7 Tb/s were transmitted over > 10 km through the atmosphere and 2 x 1.7 Tb/s were transmitted over 400 m at HHI in eye-safe conditions.

12 m-OCA 

Type: ESA 

Partner: MT Mechatronics

The objective is to reliably establish the feasibility of a
10-12 m class single-aperture optical antenna for deep-space communications within stringent financial limits and to elaborate an advanced conceptual design as a basis for its future development.
