As mobile transport networks evolve, the need for high-capacity, single-fibre bidirectional (Bi-Di) transmission links becomes increasingly critical to maintain strict timing and synchronization requirements.
In the ALLEGRO project, we are pushing the boundaries of coherent optical transmission for mobile transport links, addressing key challenges such as: ✅ Enabling compatibility with existing single-fibre infrastructures ✅ Simplifying hardware solutions to avoid costly dual-laser setups ✅ Achieving end-to-end (E2E) optical connectivity across dual and single fibre infrastructures using optical-only devices like splitters and filters
🔬 As part of our ongoing research, we conducted a laboratory test to assess the impact of reflections on BiDi transmission over single-fibre infrastructures. The study featured real-time 400G-capable coherent transceivers operating at 193.0 THz, where both upstream (US) and downstream (DS) lasers shared the same centre frequency.
📌 Our findings reveal critical insights into managing discrete and distributed reflections, ensuring optimal power efficiency without the need for additional electro-optical nodes. By leveraging coherent transceivers derived from metro core networks, we move closer to an efficient, unified transport solution for mobile networks at scale.
Stay tuned as we continue innovating towards a power-optimized, cost-effective E2E transport infrastructure! 🚀
