Prospects and Enabling Technologies Towards Multi-Tbps Long-Reach Transceivers

Summary form only given. Coherent transceiver will play a key role in 6G era. In addition to traditional long reach metro/core network, its deployment in DCI/Intra-DC and access networks has been discussed to cope with capacity-hungry AI/ML applications. However, to provide large capacity transceivers for a variety of users covering LR to ZR+ range, technical innovations are necessary to largely reduce Joule/bit and Cost/bit. In this workshop, applications and key success factor of multi-Tbps beyond 1.6Tbps (e.g. 2.4Tbps, 3.2Tbps and further) will be discussed. Possible application area and target date of multi-Tbps class transceiver will be addressed from viewpoints of various ICT services. List and share the major technical and market challenges to the realization of multi-Tbps transceivers, introduce key technology candidates to solve these challenges, and discuss the roadmap to the realization of the multi-Tbps transceivers. Topics include networking and operational technologies, transceiver architecture, signal processing technology, and optical/electrical device and their integration technology.
