论文摘要
正在为Atlas液体氩气量表II升级开发一个光学连接系统。光学链路系统负责将超过1.82,000个检测器通道的数据从1524个前端板（FEB）传输到26个光纤，每年2月150米以上的数据纤维到计数室，并带来时钟，束交叉复位信号以及缓慢的控制/监控信号返回FEB。光学链路系统基于低功率千兆收发器（LPGBT）和多功能光学收发器（VTRX+）模块，它们都是为高光度LHC升级而开发的。设计了一个评估委员会，并且正在评估光学链路系统的主要功能。本文介绍了光学链接系统的设计和主要功能的评估。
An optical link system is being developed for the ATLAS Liquid Argon Calorimeter Phase-II upgrade. The optical link system is responsible for transmit the data of over 182 thousand detector channels from 1524 Front-End Boards (FEBs) through 26 optical fibers per FEB over 150 meters to the counting room and brings clocks, bunch crossing reset signals and slow control/monitoring signals back to the FEBs. The optical link system is based on the Low-Power GigaBit Transceivers (lpGBTs) and the Versatile optical Transceiver (VTRx+) modules, which both are being developed for the High-Luminosity LHC upgrade. An evaluation board is designed and the major functions of the optical link system are being evaluated. The design of the optical link system and the evaluation of major functions are presented in the paper.
