OSC (Optical Supervisory Channel) plays a vital role in modern optical communication systems. In large-scale WDM and DWDM networks, OSC provides an independent, reliable channel for monitoring, management, and control. Therefore, even when the main service traffic experiences disruption, network visibility and operational control remain intact . Unlike service wavelengths that carry user data, OSC… Continue reading OSC: The Essential Supervisory Channel Powering Intelligent Optical Networks
