Abstract
An exemplary apparatus is provided for an optical node of an optical ring network. The optical node comprises a main branch with a wavelength blocker configured to block at least one wavelength of signals targeted to a particular node and to permit the signals received on the other wavelength channels pass, a reception unit tuned to the at least one wavelength dedicated to signals targeted to the particular node, a first optical coupler configured to transmit the signals received from a previous node of the optical ring network both to the main branch and to the reception unit, a transmission unit configured to transmit signals to a wavelength channel according to their targeted node, and a second optical coupler configured to receive the signals received from the main branch and from the transmission unit and to transmit the received signals toward a next node of the optical ring network.
