In the ALLEGRO project, we are optimizing the characterization of optical networks through a carefully designed experimental setup that enhances signal transmission and reception.
🔹 TX to RX Optical Network
The setup consists of a transmitter (TX) and receiver (RX) node, which can be directly connected end-to-end (E2E) or through an adjustable-length optical fibre for flexible testing.
🔹 Key Components & Process
✅ TX Node: A CW laser generates an optical carrier, modulated by plasmonic IQ modulators driven by an arbitrary waveform generator (AWG).
✅ Electro-Optical Conversion: Digital-to-Analog Conversion (DAC) is performed, with DSP applied for signal optimization.
✅ RX Node: The signal is detected by balanced photodetectors (B-PDs) and reconverted to the digital electrical domain using a local oscillator at the same carrier frequency. Rx-DSP further refines reception.
✅ Enhanced Signal Processing: EDFA, BPF, and VOA are integrated to strengthen the communication link, particularly for middle- and long-haul transmission.
By leveraging these advanced techniques, we are paving the way for high-performance optical communication systems with enhanced efficiency, scalability, and reliability. Excited to push the boundaries of next-gen networking!
