OPTICAL INTERCONNECT FABRICS IMPLEMENTED WITH STAR COUPLERS

摘要

This disclosure is directed to scalable optical interconnect fabrics for distributing optical signals over a computer systems. In one aspect, an optical interconnect fabric includes a star coupler and a plurality of output optical fibers. Each output optical fiber is connected at a first end to the star coupler and is connected at a second end to a node of a plurality of nodes. The fabric also includes the input optical fiber connected at a first end to the star coupler and connected at a second end to a node of the plurality of nodes. The star coupler is to receive at least one optical signal via the input optical fiber, is to split each optical signal into a plurality of optical signals with approximately the same optical power, and is to output each optical signal into one of the output optical fibers.
