As part of the ALLEGRO Horizon Europe project, we are proud to showcase the performance of our silicon nitride photonic integrated receiver by implementing the three-state time-bin BB84 protocol [Boa18]. 📡 What we’ve built:Our experimental setup integrates a full QKD...

At Allegro and Eindhoven University of Technology (TU/e), we're pushing the boundaries of quantum-safe communication by developing a versatile, photonic integrated receiver for quantum key distribution (QKD). This receiver is protocol-flexible, supporting BB84,...

In our second simulation scenario, we explored a more realistic traffic distribution:📦 50% directed to National Nodes🏢 50% routed to a Regional Datacenter We evaluated two distinct traffic splitting approaches: 🔹 P2P-split:Traffic is split at a high-capacity root...

Our latest evaluation focuses on the impact of OSNR budgets and P2P transceiver costs on total network expenditure. 🔍 Highlights from Figures 45 & 46: Figure 45 presents the distribution of P2P transceivers under OSNR degradations of:(a) 1.5 dB/span(b) 3.0...

🔬 Allegro Project Insight: Optimizing P2MP & P2P Transceivers in Metro-Core Networks In our continued exploration of OSNR-aware design, we analyzed how Point-to-Multipoint (P2MP) and Point-to-Point (P2P) transceivers behave under varying OSNR budgets. 📊 📍 Key...

In our latest simulation, we explored how traffic is routed from Aggregation Nodes to National Nodes in the backbone network. 📡 A key highlight: we analyzed transceiver cost variations as a function of the OSNR budget available at the output of the horseshoes. This...

As part of our simulation efforts in the Allegro Project, we’ve used a realistic and statistically accurate model inspired by a large macro-region of TIM’s operational metro-regional network. 🔧 Network Topology Overview: 🔹 95 core nodes: • 89 Regional nodes (66 hubs +...

As part of our ongoing work in the Allegro Project, we’ve completed an in-depth evaluation of the proposed network architecture using a realistic scenario inspired by actual metro-regional DWDM networks. 📡 The studied network architecture mirrors a real-world...

Our latest simulation results offer compelling evidence on the benefits of deploying flexible transponders in metro/regional networks. 🔧 Simulation Assumptions: OSNR degradation of 3 dB per 80 km in regional domains Adaptive modulation — lowered when OSNR drops below...

In our latest implementation phase within the Allegro project, we focused on mitigating OSNR degradations in metro/regional domains that traditionally necessitate P2P (Point-to-Point) connections. While effective, P2P introduces latency due to O/E/O conversions and...
