Evolution of Optical Access Networks and Implementing Low-Latency Transfer Systems

Optical access networks have been widespread worldwide as a means of realizing high-speed Internet connection services. They have been standardized by international organizations, and there is a trend towards increasing sophistication with the aim to increase speed and expand into various industrial fields. In this paper, authors summarize the trends in expansion of capacity and sophistication, introduce technical issues based on a representative example of sophistication, propose architecture and method for the issues. The authors implement and evaluate prototyping of a low-latency transfer system of optical access network that is connected to mobile networks.
