The potential application of advanced digital communication schemes in a future upgrade of the CMS Tracker readout optical links is currently being investigated at CERN. We show experimentally that multi-Gbit/s data rates are possible over the current 40 MSamples/s analogue optical links by employing techniques similar to those used in ADSL. The concept involves using...

Analogue and digital optical links developed at CERN are currently being integrated into the CMS Tracker in the magnet-test/cosmic challenge (MTCC), Tracker Integration Facility (TIF) and at the experiment site in Point 5. Similar activities with the same or very similar optical links are also underway for CMS ECAL as well as other CMS detector systems. Recent hardware developments...

The readout system of the ATLAS inner detector for SLHC will need to cope with ten time’s higher radiation doses than the current ATLAS inner detector readout system. It is an open question of whether the current opto-electronic readout system could be used at SLHC. We irradiated VCSEL and Si-Pin arrays at a 20 MeV neutron beam up to the levels expected at SLHC and monitored their...

We study the feasibility of fabricating an optical link for the SLHC ATLAS silicon tracker based on the curret pixel optical link architecture. The electrical signal between the current pixel modules and the optical modules is transmitted via micro-twisted cables. The optical signal between the optical modules and the data acquisition system is transmitted via rad-hard SIMM fibers...
