Biography

Haoyi Wang received the bachelor degree in Telecommunication Engineering in 2015, and a master's degree in Communication and Computer Networks Engineering in 2018, both from Politecnico di Torino, Italy. Now, she is a Ph.D. candidate in Electrical, Electronics and Communication Engineering at Politecnico di Torino, in the optical communication group. Her current research interest includes the area of high-speed optical access networks, under the supervision of Prof. Roberto Gaudino and Valter Ferrero. She also joins the project which is collaborated with Telecom Italia (TIM), on the topic of next-generation high-speed Passive Optical Networks (PON) to support 25 and 50 Gbps. A field experiment using 16 km SMF fibres between TIM research centre in Turin and Polito (PT) PhotoNext lab. The used fiber has a significant extra loss because it traverses several central offices and manholes and it is thus a good emulation of a real PON installed link. We show the coexistence of our 25G-PON proposed solution with XGS-PON commercial technology, demonstrating BM transmission for both systems and investigating the impact of residual crosstalk between them. Therefore, DPS (Digital Signal Processing) techniques is adopted to compensate for bandwidth limitations for both CM (Continuous Mode) and BM (Burst Mode) transmission, e.g., FFE (Feed-forward Equalizer) and DFE(Decision Feedback Equalizer).
