我们展示了一种光开关设计,它可以扩展到1000个端口,具有高每端口带宽(25 Gbps+)和低交换延迟(40 ns)。我们的设计采用广播和选择架构,基于无源星形耦合器和快速可调谐收发器。此外,我们采用时分复用来实现非常低的交换延迟。我们的演示展示了交换机数据平面的可行性,使用一个小型测试平台,包括两个发射器和一个接收器,通过星形耦合器连接。
We demonstrate an optical switch design that can scale up to a thousand ports with high per-port bandwidth (25 Gbps+) and low switching latency (40 ns). Our design uses a broadcast and select architecture, based on a passive star coupler and fast tunable transceivers. In addition we employ time division multiplexing to achieve very low switching latency. Our demo shows the feasibility of the switch data plane using a small testbed, comprising two transmitters and a receiver, connected through a star coupler.
