论文摘要
我们回顾了三个解决方案的低成本数据中心互连，目标范围为80公里。直接检测到的DMT，PAM-4和多波段盖是有希望的调制方案，通过组合八个56 GBIT/s的通道实现了400 Gbit/s。
We review three solutions for low-cost data center interconnects with a target reach of up to 80 km. Directly detected DMT, PAM-4 and multi-band CAP are promising modulation schemes, enabling 400 Gbit/s by combining eight channels of 56 Gbit/s.
