Abstract
The present disclosure relates to methods and systems employing a low-bandwidth, high-sensitivity telemetry signal integrated into optical line systems to dynamically optimize the launch power of an Optical Supervisory Channel (OSC) during both deployment and normal operation. Traditionally, OSC power management faces challenges such as receiver overload on short spans and insufficient received power on longer spans, requiring manual provisioning. The disclosed telemetry signal independently and reliably measures optical span loss across an extended range (up to approximately 50 dB), significantly exceeding the measurement capabilities of conventional OSC signals. Using telemetry-derived span-loss data, OSC launch power can be automatically and dynamically adjusted, protecting OSC receivers from overload damage, minimizing traffic interference, and maintaining robust OSC communications without manual intervention. The disclosure further describes integration improvements wherein telemetry and OSC functionalities reside on the same circuit pack, enabling fully automated installation, operational continuity across extreme span-loss conditions, and proactive hardware protection.
