Abstract :
The production of laser transmitters for 60000 optical links is ongoing for the CMS Experiment at CERN. A series of advance validation tests (AVTs) that assure the radiation hardness and reliability has been performed on 390 edge-emitting 1310 nm lasers taken from 13 different starting wafers, before the laser die have been assembled into final transmitters. The AVT also offered a first opportunity to characterize, with good statistics, the effects of radiation damage, annealing and accelerated aging, using a large number of laser samples.
