Abstract
There is provided mechanisms for utility communications. A method is performed by a transmitter. The method includes 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. The method includes obtaining feedback by draining a portion of the composite signal from the optical fiber. The method includes adjusting amplitude of the control and protection signal according to the portion of the composite signal.
