Paper Abstract

In the LHC experiments at CERN, spectacular amounts of data will need to be read out and stored in pipelines. A multi-level triggering system will be used to reduce the amount of data that is stored for further analysis, and the whole system, including the other experiments located on the LHC, will be synchronized to a common 40.08 MHz clock. The operating conditions inside the experiments are very harsh and the space is limited, meaning that a lot of electronics have to be located outside of the detector in control rooms 10 to 100 meters away. The relatively long distance, together with the high data rate, call for fiber optic data transmission. In this paper an overview is given of the optical link developments made for different sub-detectors of the CMS experiments.
