The evolution of metro networks continues to build on coherent single-carrier transceiver technologies, but the future lies in adaptive S-BVT transceivers powered by multicarrier technologies.
Key innovations include:
✅ VCSEL-based S-BVTs: Exploring new transmitter and receiver options for optimal performance, cost, and power efficiency.
✅ Digital Flexibility: Adaptive spectral subcarrier manipulation with optimized bit/power loading.
✅ Cost-Effective Direct Modulation & Detection: Ideal for short-reach communications, though limited for metro-core multi-hop paths.
✅ Metro-Aggregation Optimization: External modulation with tunable laser sources (TLS), combined with direct detection (DD) or direct modulation (DM) with coherent receivers (CO-Rx), enables an efficient trade-off between performance and cost.
✅ Long-Wavelength VCSEL Technology: Enhancing modulation bandwidth and enabling high-performance transmission.
By leveraging these innovations, Allegro is driving the next generation of metro networks, ensuring flexibility, efficiency, and scalability. Stay tuned for more updates!
