In the ALLEGRO project we are pushing the boundaries of VCSEL-based Bandwidth Variable Transceivers (BVTs) with advanced chirp compensation techniques. Our work focuses on optimizing the performance and adaptability of SDN-enabled S-BVTs through adaptive digital signal processing (DSP).
📡 Key Highlights of Our Approach:
- Flexible VCSEL-Based Transceivers: The multi-element BVT model consists of a transmitter (BVTx) and receiver (BVRx), ensuring adaptive and efficient optical communication.
- Adaptive OFDM Modulation: The DSP dynamically adjusts bit and power loading per subcarrier using the Levin Campello (LC) technique, considering real-time SNR estimation.
- Spectral Optimization: The LC technique provides precise spectral granularity, reaching up to 39 MHz with 512 OFDM subcarriers, utilizing a 20 GHz bandwidth.
- Advanced DSP Functions: Key functionalities include IFFT, cyclic prefix insertion, RF up-conversion, and digital-to-analog conversion (DAC) for seamless signal transformation.
🔍 Impact on Optical Networks: Our chirp-compensated VCSEL-based BVTs are designed to enhance spectral efficiency, adaptability, and network performance, ensuring cutting-edge advancements in optical transport infrastructure.
Stay tuned as we continue to drive innovation in next-generation optical transceivers!
