Abstract
Systems and methods for method for data transport using secure reconfigurable branching units, including receiving signals from a first trunk terminal and a second trunk terminal by branching units. Broadcasting is prevented for secure information delivery by dividing, within the branching units, the signals from the first trunk terminal and the second trunk terminal into three or more sections. Signals may be received from a branch terminal by one or more branching units using a single branch fiber pair, and the signals from the branch terminals may be divided into three or more groups of optical channels, wherein at least e of the channels includes dummy light. The divided signals from the first trunk terminal, the second trunk terminal, and dummy light from the branch terminal may be merged, and the merged signal sent to the branch terminal.
