Future experiments at CERN will increase the demand for high-bandwidth optical links. Custom developments for deployment within the detector volumes will be based upon commercially available transceivers.
We present our evaluation of commercial multi-Gbps optical transceivers and optoelectronic components. This serves as the basis to evaluate the performance of the future Versatile...

The ATLAS Pixel optical link connects the readout electronic in the counting room and the active detector elements.
After installation the link has been comissioned and tuned. Tests for optical and electrical functionality of components sorted out failures on the off-detector side and had the system more than 99% functional after installation.
For optical links in future detectors in...

The ATLAS has started the upgrade project to address the upgrade
of the LHC luminosity by factor of 10. ATLAS pixel tracker employs
optical links for communication between the sensors and data
acquisition. We study the radiation hardness of
PiN diodes which are part of the optical link. These components were
irradiated by 200 MeV protons up to 40 MRad and by gamma source
up to 10 MRad....

A Single-Event Upset study has been carried out on PIN photodiodes from a range of manufacturers. A total of 22 devices of eleven types from six vendors were exposed to a beam of 63MeV protons. The angle of incidence of the proton beam was varied between normal and grazing incidence for three data-rates (1.5, 2.0 and 2.5Gb/s).
We report on the cross-sections measured as well as on the...

We present the design and characterization results of different electronic building blocks for a MGy gamma radiation tolerant optoelectronic transceiver aiming at ITER applications. The circuits are implemented using the 70GHz fT SiGe HBT in a 0.35µm BiCMOS technology. A VCSEL driver circuit has been designed and measured up to a TID of 1.6 MGy and up to a bit rate of 622Mbps. No significant...
