Research on key technology and network deployment of fgOTN

With the development of 5G+ vertical industries and high-quality government-enterprise dedicated lines, the demand for fine particle business still maintains strong vitality. Starting with the technical development of fine grain optical transport network (fgOTN), the key technical schemes of fgOTN were focused on, network planning was studied, and the application scenarios of fgOTN were explored. The research provided reference ideas for operators how to deploy fgOTN in combination with the live network, so as to effectively protect network investment. Finally the deployment and application of fgOTN in domestic networks were expected to promote.
