91. The design of an optical link for the ATLAS Liquid Argon Calorimeter upgrade

Tiankuan Liu (Southern Methodist University)

Oral

We present the design of an optical link for the ATLAS liquid argon calorimeter upgrade. Challenging requirements are high data bandwidth (over 150 Gb/s raw data rate per board), radiation tolerance, low power consumption, high reliability, and low transmission latency. We discuss the link system design and component developments, especially those for the transmitting side that has to operate...

120. Laser and Photodiode Environmental Evaluation for the Versatile Link Project

Dr Jan Troska (CERN)

Oral

We summarize the results obtained in a series of radiation tests of candidate laser and photodiode components for use in the Versatile Transceiver (VTRx), the front-end component of the Versatile Link. We have carried out radiation testing at a full spectrum of sources (neutrons, pions, gammas) and can now compare the results and show that the spectrum of components that meet the radiation...

127. The Versatile Transceiver: Towards Production Readiness

Csaba Soos (CERN)

18/09/2012, 12:00

Oral

Detectors involved in the upgrade programme of the LHC will need high-speed optical links to transfer readout and control data. The link front-end will be based on a radiation tolerant opto-electronic module, the Versatile Transceiver (VTRx), developed under the Versatile Link project. In this contribution we present a test system and protocol to be used to verify the compliance of the VTRx...
