COBO Ecosystem: Post Specifications Release

Wednesday, 6 March, 10:15-11:45
Theater II, Hall E
Session organized by the Consortium for On-Board Optics (COBO)

Sesson Description

Since the release of the first Consortium for Onboard Optics (COBO) specification in 2018, many companies have initiated development of COBO compliant products. In 2019, COBO members will share their experiences in the past year and also their aspiration for the coming years on their future development. This will include development in systems, sub-systems & also both electrical and optical components.
