Optical link of the ATLAS pixel detector

Abstract The on-detector optical link of the ATLAS pixel detector contains radiation-hard receiver chips to decode bi-phase marked signals received on PIN arrays and data transmitter chips to drive VCSEL arrays. The components are mounted on hybrid boards (opto-boards). We present results from the irradiation studies with 24 GeV protons up to 32 Mrad ( 1.2 × 10 15 p / cm 2 ) and the experience from the production.
