The tracker system of the compact muon solenoid (CMS) experiment, will employ approximately 40000 analog fiber-optic data and control links. The optical readout system is responsible for converting and transmitting the electrical signals coming out from the front-end to the outside counting room. Concerning the inner part of the Tracker, about 3600 analog optohybrid circuits are involved in this tasks. These circuits have been designed and successfully produced in Italy under the responsibility of INFN Perugia CMS group, completing the volume production phase by February 2005. Environmental features, reliability, and performances of the analog optohybrid circuits have been extensively tested and qualified. This paper reviews the most relevant steps of the manufacturing and quality assurance process: from prototypes to mass-production for the final use in the CMS data acquisition system.
