Upgrade of the L2 electronics in the CMS Muon Drift Tubes system

摘要

Summary. — The excellent performance of the DT system during the past years is expected to be pursued at the increased luminosity, so the main motivation driving the DT upgrade is focused on improving the electronic system to maintain its reliability. The fulfillment of this project envisages to turn electrical signals into optical signals for a total number of 3500 optical channels that run at up to 480 Mb/s data rate. A Bit Error Rate (BER) of the order of 10~(-12) with a confidence level (CL) of 95% has been measured which ensures that an appropriate components choice has been made in view of the full boards production.
