Maxim Kuschnerov – Huawei

Bio: Maxim Kuschnerov is leading the optical research department of Huawei in Munich, Germany focusing on the topics of FTTx, data center networks, coherent optical transceivers and optical switching. He has more than 18 years of experience in research, development and product management for optical networks, working at Siemens, Nokia Siemens Networks and Coriant before joining Huawei. He is active in IEEE and OIF standardization focusing on next generation Ethernet optics using IMDD and coherent. He has authored and co-authored more than 200 publications and is holder of 15 patents. He obtained a PhD in electrical engineering from the University of the Federal Armed Forces, Munich having focused on signal processing for coherent optical transceivers.

Presentation Abstract:  The feasibility of 1.6TbE and 3.2TbE optical transceivers is analyzed given the constraints of the optical channel (CD, PMD, MPI). Requirements on transmitters and receivers (Tx optical power, Rx sensitivity, bandwidth, etc.) are discussed for legacy use cases 500m/DR, 2km/FR and a new transceiver classes like FR- or FR+ for OCS-based AI compute clusters. Limitations of intensity modulated direct detect signaling are analyzed in light of the capability of coherent optics. Considerations on modulation formats and FEC codes (performance, latency, scalability) are provided. Technological enablers (e.g. TFLN, EML) are considered
