We report a pluggable radiation-tolerant PAM4 optical transmitter module called GBT20 (Gigabit transmitter at 20 Gbps) for the high-energy physics experiments. The core of GBT20 is an ASIC GBS20. GBT20 uses an OSFP or firefly connector to input 16-bit data each at 1.28 Gbps. GBT20 drives a VCSEL die with an LC lens or a VCSEL TOSA and interfaces an optical fiber with a standard LC connector.

Future upgrades of the CERN Experiments and Accelerators require optical links capable of handling the large data volume generated in particle detectors and beam position (BPMs) sensors. Silicon Photonics optical transceivers are the best candidates to cope with the required data rate and radiation tolerance. We present the experimental characterization of Silicon optical modulators and...
The Versatile Link+ project targeting the Phase 2 HL-LHC detector upgrades has entered the production phase. After several years of prototyping and a successful pre-series production, the industrialisation of the Versatile Link+ Transceiver (VTRx+) was completed in 2021 and the VTRx+ modules are now being manufactured by an industrial partner. We describe the extensive qualification effort...
The upgrade of CERN’s accelerator complex requires improved beam instrumentation systems that will generate an increased volume of data to be transferred from the radiation areas to the back-end. A solution that increases the throughput of already deployed fibers consists in implementing the coarse wavelength division multiplexing (CWDM) technique where independent optical carriers at properly...
