ABSTRACT:
An optical network is implemented by coupling of node switches to a single waveguide. The single waveguide can be connected, tail in mouth, to provide a low loss ring concentrator to which receiving and transmitting nodes are coupled via associated node switches. A processor also may be coupled by a node switch. Alternatively, the single waveguide may terminate at the processor.
