Abstract: Methods and systems for eliminating extinguish losses in a hub ring network that includes Optical Add Drop Multiplexers (OADMs). The need for a wavelength extinguishing function is eliminated by ensuring that when a wavelength is added to the optical path at a certain node in the ring, the arriving traffic in the path before the addition does not contain that wavelength. The methods include using different wavelengths for the drop and the add operations, ensuring that a trough traffic does not include local ADD wavelengths which are subsequently combined with the through wavelengths, and bi-directional transmission on one or two separate fibers of identical dropped and added wavelengths. Systems include the use of simple, inexpensive, half or fully dynamic OADMs implementing the low-loss functionality.
