Experiences with the ATLAS pixel detector optolink and researches for future links

The optical links for the ATLAS Pixel detector has been passed several steps of development. After the design and production of the components itself, various tests have been performed on individual components on smaller or larger parts of the full system. Finally, the links were commissioned in situ after installation. A lot of experience has been gained and this should be used to step into the research on future optical links for the Pixel detector itself, but also for other detectors. In this paper the procedure of the commissioning work of the ATLAS Pixel optical link and observed issues on the system layout and function are discussed and brought into an outlook for future optical link designs.
