Abstract
Described are, among other things, a method and a receiver for receiving a management data signal in an optical transmission system where a traffic data signal is transmitted as a NRZ modulated signal. The traffic data signal has a management data signal superimposed thereon as a pulse width modulation of the symbols of the NRZ modulated signal. The NRZ modulated signal is received with the data signal superimposed thereon and the traffic data signal is recovered. The recovered traffic data signal in anti-phase is added to the received signal. The management data signal is detected from the added signals.
