Research on key technologies and applications of fgOTN for the new electric power system
Abstract
The development of the new electric power system for the future computing power access and computing power interconnection, many challenges are posed in the carrying capacity, access flexibility and multi-service adaptability of the power communication network. In view of the problems of low carrier efficiency for customer signals below 1 Gbit/s in existing optical transport network (OTN) networks, the fine grain optical transport network (fgOTN) technical system that provides fine grain service bearers had been analyzed, and the technical advantages and feasibility of fgOTN based on key technical solutions and experimental data had also been validated. The results show that fgOTN has obvious advantages in many aspects compared with the current virtual container (VC)/packet transmission (PKT)/ optical channel data unit (ODU) multi-plane OTN. How to deploy fgOTN in the existing network and network evolution will be the focus of future research.
