Description

ALICE (A Large Ion Collider Experiment) is the detector system at the LHC (Large Hadron Collider) that studies the behaviour of strongly interacting matter and the quark gluon plasma. The information sent by the sub-detectors composing ALICE are read out by DATE (Data Acquisition and Test Environment), the ALICE data acquisition software, using hundreds of multi-mode optical links called DDL (Detector Data Link). To cope with the higher luminosity of the LHC, the bandwidth of the DDL links will be upgraded in 2015. This paper will describe the evolution of the DDL protocol from 2 to 6 Gbit/s
