Introduction to the Exhibition Area - Exploring the Technologies

The "Exploring the Technologies" area details the lineage of technological development in each technical field. Each floor also features "Approaches" showcasing key notable exhibits$2014be sure to visit them.

^{Technologies that Link and Connect Two Points}
Technologies of Nodes(Switchin system, software)[1F]

This section introduces the "switching" technologies that connect phones.When telephone service began, manual switching was performed by telephone operators, but they were gradually replaced by automatic switching systems.Subsequently, to support wider use of telecommunications beyond just voice transmission, switching systems evolved to provide higher speed and performance.

^{Buildings and power facilities supporting telecommunications}
Technologies of Facilities [1F]

Buildings that house essential telecommunications equipment and facilities have also evolved over time to meet various requirements, including durability, functionality, and energy supply.

^{Technologies that Link and Connect Two Points}
Access System and Outside Plant Inftastructure Technologies[2F]

This section gathers technologies related to the part of the telecommunications network known as the "access network", which connects switches to communication devices used by individuals, households, and businesses, such as telephones, smartphones, and ONUs.Here we use dynamic exhibits to introduce various transmission technologies designed to deliver a large volume of information within tight space constraints, alongside civil engineering technologies that build and protect the routes connecting users to buildings housing switches.
