Abstract
A branch-ring optical network and a technique for manufacturing a branch-ring optical network are disclosed. By connecting an outgoing optical conduit to a number of ports and one or more diffraction-grating based add/drop modules, and coupling the first distribution-node to at least one or more distribution-end-nodes having one or more diffraction-grating based add/drop modules, a branch-ring optical network that is easily constructed and maintained is formed.
