Recent research activities in optical communication are focused on high-speed short range connections. Especially the increasing demand for high-speed data centers communication, with the overall goal of terabit data rates, is the driving force. Compared to long-haul systems, where complex optics and modulation formats are used, a simpler approach is necessary taking into account the cost aspect and the use of standard optical components.In this project, the potential of different techniques for terabit data center communication, for link lengths of 1m to 1km shall be studied. Possible approaches here are an increased modulation bandwidth, the use of higher modulation formats, advanced channel coding in combination with feedback and link adaptation. Additionally, different multiplexing formats will be investigated, with a particular focus on the requirements for data center communications. A general approach in this project will be the use of high-speed digital signal processing in combination with standard electrical and optical components.

光通信中的最近研究活动集中在高速短程连接上。特别是对高速数据中心通信的需求不断增长，总体目标是太比特数据速率，这是推动力。与使用复杂的光学和调制格式的长途系统相比，考虑到成本方面和标准光学部件的使用，有必要采用一种更简单的方法，在本项目中，将研究链路长度为1米至1公里的太比特数据中心通信的不同技术的潜力。这里可能的方法是增加调制带宽、使用更高的调制格式、与反馈和链路自适应相结合的高级信道编码。此外，还将研究不同的多路复用格式，特别关注数据中心通信的要求。该项目的一般方法将是结合标准电气和光学组件使用高速数字信号处理。
