New fiber optical transceivers, opto-boards, were designed and produced to replace the first generation opto-boards installed in the ATLAS pixel detector and for the new pixel layer, the insertable barrel layer (IBL). Each opto-board contains one 12-channel PIN array and two 12-channel VCSEL arrays along with associated receiver and driver ASICs. The new optoboard design benefits from the production and operational experience of the first generation opto-boards and contains several

Additionally, a set of the new opto-boards have been subjected to an accelerated lifetime experiment at 85 C and 85% relative humidity for over 1,000 hours. No failures were observed. We are cautiously optimistic that the new opto-boards will survive until the shutdown for the detector upgrade for the high-luminosity Large Hadron Collider (HL-LHC).
