Chirp-Dispersion Interaction-Enabled Uneven Optical PAM-4 Based on Dual-Drive MZM for 5.9-dB SNR Gain in Digital RoF Fronthaul With Quantizer Compatibility (W2B.25)
Presenter: Yimin Hu, Shanghai Jiao Tong University
We theoretically model and explain the dispersion-induced eye closure/open in dual-drive MZM-based system and leverage the effect for uneven optical PAM-4 digital radio-over-fiber fronthaul. We evaluated two quantizers and 5.9-dB SNR gain is experimentally achieved.
