Radiation test of commercial of the shelf (COTS) optical transceivers in the frame of the beam position monitor (BPM) consolidation project for the Large Hadron Collider (LHC)

Abstract

The consolidation of the Large Hadron Collider (LHC) beam position monitor (BPM) requires the deployment of about 5000 single-mode radiation-tolerant optical transmitters, working at 10 Gbps during 20 years of operation. While the use of the custom devices being designed at CERN remains the baseline for the project, 8 commercial of the shelf (COTS) optical transceivers have been evaluated as an alternative. This paper presents the results of the full characterization in radiation of these COTS devices, including cumulative effects and single event effects (SEE), evaluated during both data transmission and reception.
