论文摘要
为Atlas液体氩热量表2升级开发了原型的光学链接板。该板由24个LPGBT芯片和8个VTRX+模块组成,并演示了未来前端板的完整光学链接设计。董事会在传输检测器数据中有22个单纯链接,这些探测器数据是在FPGA中模拟的,并通过6个FMC连接器注入了探测器电子设备。董事会通过冗余设计实现2个用于时钟,控制和监视的双面光学链接,以提高系统的可靠性。数据传输和所有冗余设计均已验证。一个纤维路由方案,其中2或3个VTRX+模块与MPO连接器重新连接到前面板。
A prototype optical-link board has been developed for the ATLAS Liquid Argon Calorimeter Phase-2 upgrade. The board consists of 24 lpGBT chips and 8 VTRx+ modules and demonstrates the full optical link design of the future front-end board. The board has 22 simplex optical links to transmit detector data, which are emulated in FPGAs and injected through 6 FMC connectors, to the off-detector electronics. The board implements 2 duplex optical links for clocks, control, and monitoring with redundant design to improve the system reliability. Data transmission and all redundant designs have been verified. A fiber routing scheme, in which 2 or 3 VTRx+ modules are re-connected to the front panel with an MPO connector, has been prototyped.
