Disaggregated and transparent multi-band optical continuum across access, horseshoe aggregation, and metro IPoWDM networks
The limitations of segmented and power-inefficient legacy optical networks underscore the need for a disaggregated, transparent multi-band optical continuum spanning access, aggregation, and metro domains.

| Sumario: | The limitations of segmented and power-inefficient legacy optical networks underscore the need for a disaggregated, transparent multi-band optical continuum spanning access, aggregation, and metro domains. In this work, we demonstrate the first field trial, to our knowledge, of a disaggregated and transparent multi-band optical network interconnecting access, aggregation, and metro segments over both the C- and O-bands. The proposed architecture extends the optical continuum from antenna sites through O-band access links to aggregation hubs, and further into a C-band metro-core network, eliminating intermediate opto-electronic conversions. The data plane integrates SOA-based O-band switching for dynamic signal routing and loss compensation, while the control plane is realized through an innovative hierarchical SDN-based solution. This control plane orchestrates end-to-end transparent paths across multiple domains, spectral bands, and layers, leveraging standardized protocols and models for interoperability. Experimental validation shows the seamless multi-band interconnection, demonstrating effective multi-domain orchestration, optical transparency, and control scalability. |
