Abstract :
The optical supervisory channel (OSC) in WDM (Wavelength Division Multiplexing) transmission systems is used for OAM (Operations, Administrations and Management) function like overhead information in SOH (Synchronous Digital Hierarchy). We present supervisory information contents and alarm propagation procedure in our 1.6T WDM transmission system. Also, this paper describes the OSC frame structure and the OSC subsystem configuration that can provide reliable and effective operation and maintenance capability.
