Embodiments of the present invention are directed to high-bandwidth, low-latency optical fabrics for broadcasting between nodes. In one embodiment, an optical fabric includes an optical communication path optically coupled to a broadcasting node and optically coupled to one or more broadcast receiving nodes. The optical fabric also includes a first optical element optically coupled to the optical communication path and configured to broadcast an optical signal generated by the broadcasting nodes onto the optical communication path, and one or more optical elements optically coupled to the optical communication path and configured to divert a portion the broadcast optical signal onto each of the one or more receiving nodes.
