🔬 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 findings (Figure 44 & 45):
- With an OSNR degradation of 3 dB per span, the number of P2MP transceivers initially decreases, stabilizing at its lowest value when the OSNR budget reaches 4.5 dB, which corresponds to ~120 km of metro-core reach.
- P2P transceivers, dominant in the baseline architecture, are progressively eliminated as higher OSNR budgets allow direct reach to National Nodes.
- Minimum cost conditions are achieved at OSNR budgets of:
- 4.5 dB for 1.5 dB/span degradation (~190 km),
- 7.5 dB for 3.0 dB/span (~210 km),
- 10.5 dB for 4.5 dB/span (~240 km).
These results highlight how OSNR-aware light-tree designs not only extend reach but significantly reduce network costs by phasing out redundant transceivers. 🌍🔗
