The Optoboard System is the data aggregation and signal conversion stage of the ATLAS ITk Pixel data transmission chain. The basic working principle is:
One Optoboard consists of:
Specific for SLAC's test-Optopanel will be marked in red .
4x Optoboards are housed in one Optobox. This Optobox is housed in a Test-Optopanel.
Please refer to our Interface Document here. All the connectors of the Optoboard System is explained there.
All schematics for all of Berns designed PCBs can be found here.
We collect support requests and general questions on our Mattermost channel Bern-Optoboard (invite link).
We created a repository with scripting software to easily configure the Optoboard: https://gitlab.cern.ch/bat/optoboard_felix. A lot is documented in the readme and wiki of the repository.
In a currently ongoing effort by Bern PhD student Daniele dal Santo, the software will be integrated into the ITk demonstrator software itk-demo-sw.
The test-Optopanel houses one Optobox with 4 Optoboards. It has a twinax inlet (round) and a fibre outlet (rectangle). The Optobox is mounted on a cooling plate with two 8 mm pipes. The
A collection of photographs from the test-Optopanel and its sister at CERN SR1 can be found here. See also this Twiki here of the SR1 test-Optopanel which has similiar information (but some very different configurations).

Currently no MOPS is mounted on the Powerboard inside the test-Optopanel (due to availability). We will ship one as soon as we got our hands on them.
