Abstract

Very high speed PON is the PON generation in the ITU-T that is coming after 50G-PON. It is currently in the exploratory study phase in ITU, with network operators sharing their views on potential requirements and the Q2/SG15 group proposing and evaluating technology candidates to meet these requirements. This paper reviews the progress so far in identifying the key requirements, technical candidates, physical layer transmission performance, and the related technology maturity. The paper discusses the technology candidate evaluation process underway as part of this pre-standardization, research phase of very high speed PON among the relevant standards experts within FSAN and ITU-T SG15/Q2.

期刊介绍： The scope of the Journal includes advances in the state-of-the-art of optical networking science, technology, and engineering. Both theoretical contributions (including new techniques, concepts, analyses, and economic studies) and practical contributions (including optical networking experiments, prototypes, and new applications) are encouraged. Subareas of interest include the architecture and design of optical networks, optical network survivability and security, software-defined optical networking, elastic optical networks, data and control plane advances, network management related innovation, and optical access networks. Enabling technologies and their applications are suitable topics only if the results are shown to directly impact optical networking beyond simple point-to-point networks.
