The miniaturised optical transceiver module, developed in the framework of the Versatile Link PLUS project (VL+) will be installed in the upgraded detector front-ends at the HL-LHC. The modules will have to operate over a wide temperature range (-35 °C to +60 °C). We describe the impact of the temperature on the performance of the transceiver and we present simulation and measurement results obtained during the thermal characterisation of different transceiver prototypes.
