P o S ( T W E P P 2 0 1 9 ) 0 5 5 Versatile Link + Transceiver Production Readiness

The Versatile Link+ project is about to enter its production phase, ready for the Phase 2 HL-LHC detector upgrades. We present the status of the front-end part of the Versatile Link+ project: the Versatile Link+ Transceiver, which provides a low-mass, radiation tolerant, optical transmitand receive module for tight integration in the upgrading HL-LHC detectors. We describe the development and thorough testing carried out with the transceiver prototypes and their sub-components and the design decisions that have led to the final production-ready prototype. The planned production schedule is also presented.
