After Run III, ending in 2026, the ATLAS detector at the LHC will undergo a series of upgrades to cope with the harsher radiation environment and increased number of proton interactions in the High Luminosity-LHC, from approx 60 to 200, that will start operation in 2029. One of the key projects in this suite of upgrades is the ATLAS Inner Tracker (ITk). The current tracker will be completely replaced by a full-silicon setup based on pixels and strips. The pixel detector of the ITk must be read out accurately and with extremely high rate. The Optosystem performs optical-to-electrical conversion of signals from the pixel modules. This talk will give an overview of the ATLAS ITk pixel detector and in more detail presents recent results related to the performance of the data transmission chain pivoted on the Optoboards and to the design, testing and production of the Optopanels.
