We report on our recent progress in developing an optical transmission system based on wavelength division multiplexing (WDM) to enhance the read-out data rate of future particle detectors. The design and experimental results of the prototype of a monolithically integrated multi-wavelength transmitter are presented as well as temperature studies of electro-optic modulators and optical...
The Versatile Link PLUS project (VL+) targets the phase II upgrades of the ATLAS and CMS experiments. It will develop a radiation resistant optical link, operating at up to 10Gbps in the upstream and 5Gbps in the downstream directions with a smaller footprint and higher channel count than its predecessor. A low-profile package is being developed that allows volume production at reduced costs,...
Many experiments require high data rates, implying custom link design using transmission line theory.
Transmission line theory is presented including FEA analysis of energy dissipation in exemplar designs. The choice of transmission line designs are reviewed.
Transmission line design principals and testing equipment are presented. The characterisation techniques of time-domain reflectometry...
The TTC-PON (Timing, Trigger and Control system based in passive optical networks) was first investigated in 2010 in order to replace the current TTC system, responsible for delivering the bunch clock, trigger and control commands to the LHC experiments. A new prototype of the TTC-PON system is now proposed, overcoming the limitations of the formerly presented solutions. A new upstream data...
