Abstract :
A new in-channel monitoring technique for transparent networks using a high-frequency digital control signal for optical performance monitoring and channel identification is investigated experimentally. A client independent overhead channel is established that serves as an early warning function for client channel performance degradation due to amplified spontaneous emission noise and self-phase modulation
