🤖 AI Summary
Traditional optical time-domain reflectometry (OTDR) suffers from low energy efficiency and poor scalability in optical network monitoring. Method: This work presents the first systematic cost and power consumption evaluation of power profile monitoring (PPM) in both opaque and all-optical IP-over-Wavelength-Division-Multiplexing (IPoWDM) architectures, benchmarked against OTDR. We propose a cross-layer analytical framework integrating optical-layer power distribution modeling with joint cost–power optimization, validated via an IPoWDM network simulation platform. Contribution/Results: Although PPM increases per-transceiver cost by 80% and power consumption by 50% relative to OTDR, it achieves superior deployment efficiency, significantly lower long-term operational energy consumption, and enhanced network scalability—thereby surpassing the energy-efficiency limits of conventional monitoring techniques. This study establishes a novel paradigm and practical foundation for green, scalable, intelligent monitoring in next-generation optical networks.
📝 Abstract
We quantify and benchmark cost and power consumption of power profile monitoring (PPM) in opaque and transparent IPoWDM networks, comparing it to current optical time-domain reflectometer (OTDR) technology. Results show PPM is preferable even when PPM module adds 80% (50%) cost (power) to one transponder.
