论文摘要
使用850 nm多模式垂直腔发射激光器（VCSELS）的光学链路的发展已速度提高到25 Gbps。对于高能实验中的应用，收发器必须在辐射和粒子场中耐受性。我们报告了名为MTX+的微型发射器的原型制作，该发射器是通过双通道激光驱动器locld65和850 nm VCSEL开发的，该发射速率是高速传输的。 Locld65在TSMC 65 nm过程中制造，并在QFN-40中包装以进行组装。 MTX+模块和测试套件首先是使用PCB和有资格使用10 Gbps应用程序的组件制成的，并经过实现14 Gbps的测试。 MTX+模块的数据传输速率进一步研究了25 Gbps的速度。使用Layout后模拟检查Locld65，并使用包括有资格使用25 Gbps应用程序的TOSA的组件进行升级的模块设计。 PCB材料被Panasonic Megtron6取代。修订后的MTX+以25 Gbps进行了测试，而眼睛示意图显示面罩边缘为22％。
Development of optical links with 850 nm multi-mode vertical-cavity surface-emitting lasers (VCSELs) has advanced to 25 Gbps in speed. For applications in high-energy experiments, the transceivers are required to be tolerant in radiation and particle fields. We report on prototyping of a miniature transmitter named MTx+, which is developed for high speed transmission with the dual-channel laser driver LOCld65 and 850 nm VCSELs packaged in TOSA format. The LOCld65 is fabricated in the TSMC 65 nm process and is packaged in the QFN-40 for assembly. The MTx+ modules and test kits were first made with PCB and components qualified for 10 Gbps applications, and were tested for achieving 14 Gbps. The data transfer rate of the MTx+ module is investigated further for the speed of up to 25 Gbps. The LOCld65 is examined with post-layout simulation and the module design upgraded with components including the TOSA qualified for 25 Gbps applications. The PCB material is replaced by the Panasonic MEGTRON6. The revised MTx+ is tested at 25 Gbps and the eye-diagram shows a mask margin of 22 %.
