The invention refers to a optical communication network comprising a monitoring node having a port for outputting at least one optical signal that has a first wavelength range over an optical link of the network to a reflector node of the network. In order to allow for efficient monitoring the optical link it is suggested that the reflector node comprises a wavelength selective optical reflector connected to the link, the reflector being configured for generating a monitoring signal by reflecting a part of the optical signal back into the link, the monitoring signal having a second wavelength range that is a proper sub-range of the first wavelength range and the monitoring node comprises a detector coupled with the port for determining whether the link is defective arranged for detecting the monitoring signal generated by the reflector node.
