High speed ribbon optical link for the level 0 muon trigger

In this note we present the design of a high speed optical link which are foreseen to transfer data required by LHCb muon trigger. It is based on ribbon optical link and includes components to reduce the jitter of the TTC clock. We also describe the prototype board used to test and characterize such ribbon optical link. We measure a bit error rate below 10-15 at 1.6 Gbit/s. It is rather insensitive to the noise of the power supplies and the jitter of the input clock. The effect of single event upsets was estimated on the part of the ribbon optical link which will be implemented in the muon front-end electronics. We obtained an equivalent bit error rate of 3´10-11 in the radiation environment of the muon detector.
