Asynchronous Optical Traffic Offloading of Hybrid Optical/Electrical Data Center Networks

In this paper, we discuss the challenges and limitations of current free-space optical (FSO) networks toward scaling beyond the 100 Gbps switch capacity era while achieving low-latency and high-reliability. Owing to the slowdown of Moore’s law, to avoid electronically-induced bottlenecks, we construct an FSO switch network and experimentally evaluate the feasibility of ultrafast optical packet switch architecture based on polarization-independent plomb lanthanum zirconate titanate (PLZT) switch without buffering. The bit error ratio of 160 Gbps ([Formula: see text]) data was validated based on measurements while still preserving the sub-us latency metrics ([Formula: see text] ns). The experimental results may offer a significant reference for FSO communication and network.
