The ATLAS phase-I upgrade aims to enhance event trigger performance in the Liquid Argon (LAr) calorimeter and the forward muon spectrometer. The trigger signals are transmitted by optical transceivers at 5.12 Gbps per channel in a radiation field. We report the design, quality control in production and aging test of the transceivers fabricated with the LOCld laser driver and multi-mode 850 nm vertical-cavity surface-emitting laser (VCSEL). The modules are packaged in miniature formats of dual-channel transmitter (MTx) and transceiver (MTRx) for the LAr. The transmitters are also packaged in small form-factor pluggable (SFP) for the muon spectrometer. In production, the LOCld chips and VCSELs in TOSA package were examined before assembly. All of the modules were tested and selected during production for quality control based on the eye-diagram parameters of outputs. The yield is 98 % for both the MTx and MTRx on a total 4.7k modules. The uniformity of transmitter channels of a MTx was assured by choosing the TOSA components with approximately equal light powers. The aging effect is monitored in burn-in of a small batch of transmitter modules with bit-error test and eye-diagrams measured periodically. The observables are stable with the light power degradation within 5 % over a period of more than 6k hours.

ATLAS的第一阶段升级旨在增强液氩（LAr）量热仪和前向μ子光谱仪中的事件触发性能。触发信号由光收发器在辐射场中以每通道5.12 Gbps的速率发送。我们报告了使用LOCld激光驱动器和多模850 nm垂直腔面发射激光器（VCSEL）制造的收发器的设计，生产过程中的质量控制和老化测试。这些模块以用于LAr的双通道发送器（MTx）和收发器（MTRx）的微型格式包装。发射器还封装在用于μon光谱仪的小型可插拔（SFP）中。在生产中，组装前已检查了TOSA封装中的LOCld芯片和VCSEL。所有模块都在生产过程中经过测试和选择，以根据输出的眼图参数进行质量控制。在总共4.7k个模块上，MTx和MTRx的产率均为98％。通过选择具有近似相等光功率的TOSA组件，可以确保MTx发射器通道的一致性。在少量发射机模块的老化过程中，通过比特错误测试和眼图定期监测老化效果。在超过6k小时的时间内，可观察到的光功率衰减在5％之内是稳定的。在少量发射机模块的老化过程中，通过比特错误测试和眼图定期监测老化效果。在超过6k小时的时间内，可观察到的光功率衰减在5％之内是稳定的。在少量发射机模块的老化过程中，通过比特错误测试和眼图定期监测老化效果。在超过6k小时的时间内，可观察到的光功率衰减在5％之内是稳定的。
