Integrated Components and Solutions for High-Speed Short-Reach Data Transmission

According to different transmission distances, application scenarios of a data center mainly include intra- and inter-data optical interconnects. The intra-data interconnect is considered as few kilometers between servers racks inside center, which accounts for nearly 80% traffic center. other one, interconnect, applied in tens among centers. Since exchange centers generally occurs many racks, lot transmitter receiver components are required, interconnects become highly sensitive component costs. In this paper, we firstly review the development applications mainstream (e.g., VCSEL, DML, EML, MZM, monolithic integrated transmitter) single-end photodetector, Kramers-Kronig receiver, Stokes vector receiver), have been widely short-reach systems. Then, two types solutions including simplified detection scheme transceiver integration presented detail. Finally, summarize discuss technological options distances. We believe that components, especially integration, will powerful solution next-generation high-speed
