11. A line module in a terminal node of an optical network, comprising:
a coherent optical transceiver comprising a laser operable to supply an optical signal, the laser having an activation state being activated or deactivated;
a line port configured to be connected to an optical fiber;
an embedded device; and
a real time processor dedicated to protection signaling mechanisms within the optical network;
wherein the embedded device is operable to detect a fault in the optical fiber and, responsive to detecting the fault, transmit a first fault signal to the real time processor; and
wherein the real time processor is operable to receive one of the first fault signal and a second fault signal, and, responsive to receiving the first fault signal or the second fault signal, trigger the embedded device to switch the activation state of the laser, and, further responsive to receiving the first fault signal, generate a third fault signal and transmit the third fault signal.
