Abstract:
1. A method for forming a branch-ring optical network, comprising: connecting an outgoing optical conduit to a distribution-node, wherein the distribution-node comprises an outbound receiving port for receiving optical communication signals from a hub, an outbound transmitting port, a return receiving port, a return transmitting port, and an add/drop module; coupling the distribution-node to a distribution-end-node, wherein the distribution-end-node includes and utilizes a plurality of ports consisting of one outbound receiving port and one return transmitting port, wherein the distribution-end-node transmits to the hub via the return transmitting port of the distribution-end-node an optical communication signal received from the distribution-node via the outbound receiving port of the distribution-end-node, wherein the optical communication signal is transmitted from the return transmitting port of the distribution-end-node to the hub over a return path that traverses the return receiving port and the return transmitting port of the distribution-node, wherein the return path does not include any add-drop modules.
