Test of the optical links for ATLAS IBL — •Rouhina Behpour, Peter Maettig, Tobias Flick, and Marius Wensing — Wuppertal University,Gaussstrasse 20, 42119 Wuppertal

An important sub-system of the ATLAS detector at the LHC is the pixel detector which is presently being upgraded with a new layer called Insertable B-layer (IBL). The readout data from the detector and the command messages are transmitted via optical links. To increase the bandwidths, improved read-out components have to be developed. Between the Back of Crate card at the off-detector side and the optoboard at the on-detector side signals are transmitted via optical fibers at up to 160 Mb/s. To test the signal quality and reliability of the optical transmission path, a test system has been constructed at Wuppertal university. The test system, the test requirements and the results will be presented.
