Evaluation of 400m, 5Gbit Versatile Link lengths over OM3 and OM4 fibres for the LHCb upgrade

Abstract : The LHCb experiment will upgrade its DAQ system to a trigger less, 40MHz read-out after LS2. To be able to process the approximately 40Tbit/s of data we will require a massive computing farm. This computing farm can not be installed underground, in the vicinity of the detector anymore due to the enormous power and cooling requirements. An affordable data transport solution has to be found to carry the data from the detector to the new data center on the surface. The distance to cover is estimated to be between 300 and 400 meters. We evaluated the feasibility of using the 5Gbit/s Versatile Link to cover the full distance over OM3 and OM4 quality fibres and will present our results.
