1. A method for utility communications, the method being performed by a transmitter, the method comprising:
- superimposing a control and protection signal for utility communications on top of an existing optical signal transmitted over an optical fiber to form a composite signal, wherein the control and protection signal has lower bit rate than the existing optical signal, and wherein the utility communications relate to remote control of unmanned stations and transfer of data and load values;
obtaining feedback by draining a portion of the composite signal from the optical fiber; and
adjusting amplitude of the control and protection signal according to said portion of the composite signal.
