   Presenter: Hanyu Gao, Sun Yat-sen University, China

    Presentation Details   Paper

   This paper demonstrates the first field trial of autonomous lightpath configuration over an SDM network using 7-core fibers. With a composable-ML-based configuration algorithm, ~10-second lightpath provisioning and automated failover are achieved while desirable QoT is secured.Authors: Hanyu Gao, Sun Yat-sen University / Xiaoliang Chen, Sun Yat-sen University / Wenbang Zheng, Sun Yat-sen University / Chen Yingyu, Sun Yat-sen University / Yongguang Xiao, Sun Yat-sen University / Zhaohui Li, Sun Yat-sen University

   Colorless and Directionless ROADM for Meshed Coupled-Core Multicore Fiber Networks

   Presenter: Ruben Luis, NICT, Japan

    Presentation Details   Paper

   We demonstrate the first meshed spatial-super-channel switching SDM network using field-deployed coupled-core multicore fibers with a 3 line-side, colorless, directionless ROADM. We evaluate 19 network scenarios including add&drop, bypass and grooming with 2 Tb/s granularity.Authors: Ruben Luis, NICT / Gaimmarco Di Sciullo, University of L'Aquila / Georg Rademacher, NICT / Benjamin Puttnam, NICT / Andrea Marotta, University of L'Aquila / Robert Emmerich, Fraunhofer Institute for Telecommunications / Nicolas Braig-Christophersen, Fraunhofer Institute for Telecommunications / Ralf Stolte, Finisar Australia / Fabio Graziosi, University of L'Aquila / Antonio Mecozzi, University of L'Aquila / Colja Schubert, Fraunhofer Institute for Telecommunications / Tetsuya Hayashi, Sumitomo Electric Industries, Ltd. / Takuji Nagashima, Sumitomo Electric Industries, Ltd. / Cristian Antonelli, University of L'Aquila / Hideaki Furukawa, NICT

   Photonics-Assisted 320 GHz THz-Band 50 Gbit/s Signal Outdoor Wireless Communication Over 850 Meters

   Presenter: Weiping Li, Fudan university, China

    Presentation Details   Paper

   We have experimentally demonstrated, for the first time, a single-channel 50 Gbit/s net rate THz-band transmission over an 850 m wireless link, which also creates the longest wireless distance and largest distance-rate product for a photonic THz-wireless transmission in the world.Authors: Weiping Li, Fudan university / Jianjun Yu, Fudan university / Bowen Zhu, Fudan university / Jiao Zhang, Purple Mountain Laboratories / Min Zhu, Purple Mountain Laboratories / Feng Zhao, Xi’an University of Posts and Telecommunications / Tangyao Xie, Beijing University of Posts and Telecommunications / KAIHUI WANG, Fudan university / Yi Wei, Fudan university / Xiongwei Yang, Fudan university / Bingchang Hua, Purple Mountain Laboratories / Mingzheng Lei, Purple Mountain Laboratories / Yuancheng Cai, Purple Mountain Laboratories / Wen Zhou, Fudan university / Jianguo Yu, Beijing University of Posts and Telecommunications

   203.6Tb/s CPRI-Equivalent Rate 1024-QAM DA-RoF Fronthaul With Comb-Based WDM and SDM Superchannel

   Presenter: Yixiao Zhu, Shanghai Jiao Tong University, China

    Presentation Details   Paper

   We demonstrate 203.6Tb/s CPRI-equivalent-rate 1024-QAM self-homodyne fronthaul using digital-analog radio-over-fiber and comb-based SDM and WDM superchannel from a single laser source. We further present new records from 309.4Tb/s CPRI-equivalent-rate with 256-QAM to 81.6Tb/s with 1048576-QAM.Authors: Yixiao Zhu, Shanghai Jiao Tong University / Chenbo Zhang, Peking University / Jingjing Lin, Peking University / Yicheng Xu, Shanghai Jiao Tong University / Qunbi Zhuge, Shanghai Jiao Tong University / Weiwei Hu, Peking University / Zhangyuan Chen, Peking University / Weisheng Hu, Shanghai Jiao Tong University / Xiaopeng Xie, Peking University
