A system, a line module in a terminal node of an optical network, and/or a method are described in which a first embedded device of a first line module transmits a first fault signal to a first real time processor of the first line module. In response, the first real time processor triggers the first embedded device to deactivate a first laser of a first coherent optical transceiver of the first line module and transmits a second fault signal to a second real time processor of a second line module. In response, the second real time processor triggers a second embedded device of the second line module to activate a second laser of a second coherent optical transceiver of the second line module. The first laser and the second laser may be operable to supply a first optical signal and a second optical signal, respectively.
