Network Configuration

According to the joint statement, the metro network features a configuration that integrates the IP layer and optical transmission layer using Cisco NCS5500 series routers, capable of directly transmitting and receiving optical signals for WDM, and Fujitsu’s 1FINITY series Open Line System (OLS), which can connect to other companies’ products through an open interface.

Expansion Plans and Response to 5G

KDDI plans to deploy the metro network across Japan by the end of fiscal 2028. A Fujitsu press release noted that with the nationwide rollout of 5G services in Japan, now in widespread use, the number of users of video and other data-intensive services is increasing, leading to a growth in the volume of communications. The new configuration also makes it easier to expand capacity, enabling a rapid response to increases in communications traffic.
