Radiation-hard high speed data links play an ever growing role in modern experiments. The state-ofthe-art marked by the lp-GBT under development for the LHC Phase-II upgrades, provides data rates of 10 Gb/s and stands radiation levels of 1 MGy
Two lines of R&D activities have been identified to bring the performance of high-speed data links to the levels required by future detectors, namely Optoelectronics and FPGAs.
