Abstract

The present invention refers to an optical node (N1) destined to be implemented in an optical ring network (1) comprising links (L1...L4) configured for transmitting a plurality of multiplexed wavelength channels (») wherein at least one wavelength channel (»1) is dedicated to signals targeted to a particular node (N1) wherein the optical node (N1) comprises: - a main branch (9) with a wavelength blocker (11) configured for blocking the at least one wavelength of the signals targeted to the node and for letting the signals received on the other wavelength channels pass, - a reception unit (7) tuned to the at least one wavelength (»1) dedicated to signals targeted to the node (N1), - a first optical coupler (5) configured for transmitting the signals received from a previous node (N4) of the optical ring network (1) both to the main branch (9) of the node and to the reception unit (7), - a transmission unit (19) combined with the reception unit (7) and configured for transmitting signals to a wavelength channel (»2...»4) according to their targeted node (N2...N4), - a second optical coupler (17) configured for receiving the signals received both from the main branch (9) and from the transmission unit (17) and for transmitting the received signals toward a next node (N2) of the optical ring network (1).
