Abstract

We disclose communication methods using which a cluster of network nodes is interconnected via an optical interconnect and an electrical switch engine. A communication method executed at a master optical transceiver coupled to one side of the optical interconnect enables that transceiver to establish an optical communication link with any one of a plurality of slave optical transceivers coupled to the other side of the optical interconnect. A communication method executed at a slave optical transceiver enables that transceiver to communicate with the master optical transceivers without having its own light source and, instead, modulating data onto previously un-modulated signaling dimensions of the incoming optical waveforms, which are then turned around and broadcast back to the master optical transceivers. Some embodiments enable the slave optical transceivers to establish a temporary fully switchable network for the corresponding network nodes, wherein the switching is performed by electrically switching the electrical switch engine.
