Abstract

The technology described herein is generally directed towards an integrated high-radix strictly non-blocking optical switching fabric, such as for use for intra-rack communication within racks in a data center. The fabric may be configured with any number of ports. A general topology of optical components, along with a routing controller (e.g., algorithm/mechanism), results in an optical switching fabric architecture that provides bidirectional routing, in a high-performance, high bandwidth, highly robust switching fabric that is also low in power consumption and low latency.
