ARTERIA Networks Corporation (headquarters: Minato-ku, Tokyo; President & CEO: Tatsuya Abe; hereinafter, “ARTERIA”) and AT TOKYO Corporation (headquarters: Koto-ku, Tokyo; President & CEO: Tatsuya Izumida; hereinafter, ”AT TOKYO”) have entered into an agreement (hereinafter, “Agreement”) on the installation and use of communication cable facilities, and set to install the first*1 optical fiber cable to traverse the Tokyo Port. This new cable will link the Toyosu-Ariake and Shibaura-Shinagawa areas, where many IT companies are concentrated.
Background
Infrastructure for communications has become essential in supporting our daily lives, not only for calls and internet connections, but also in many other aspects such as cashless payments, security, disaster prevention, and the use of cloud services. Also, the recent workstyle reforms, the increase of rich content such as video streaming, and the widespread adoption of DX, AI, and IoT upsurge the communication traffic in data centers where such data is accumulated, underlining the urgency of enhancing the infrastructure that supports these communications.
In response to such demands, ARTERIA and AT TOKYO have entered into this Agreement to install an optical fiber communications cable that will cross the Tokyo Port using the Horizontal Directional Drilling method (hereinafter, “HDD method”*2). AT TOKYO will establish its Chuo Center #3 in the Shibaura-Shinagawa area by July 2024 as a network connection hub alongside its existing data centers, supporting information infrastructure in Tokyo where major financial institutions, content providers, and telecommunications companies from not only Japan, but also from Asia and rest of the world converge. ARTERIA, as a leading communications infrastructure service provider, will connect the IT companies in Toyosu-Ariake area to the new AT TOKYO data center in the Shibaura-Shinagawa area via a high-capacity, low-latency, and shortest cable route, thereby supporting businesses in Tokyo that serves as a hub for high-tech and international financial industries.
The benefits of connecting to surrounding data centers via the Tokyo Port cross-route
■Enhanced availability through redundant land and marine routes provides a highly resilient communications network
With the installation of this optical fiber communications cable, the Toyosu-Ariake area and the Shibaura-Shinagawa area will be connected via redundant land and marine routes, increasing the resilience and availability of the network infrastructure. Relying solely on existing land routes poses certain risks such as flooding and liquefaction during disasters, leading to potential network disruptions in emergencies. Using the HDD method allows a continuous underground pipeline in submarine areas that ensures high-speed, high-capacity fiber optic communications while preventing cable damage by ship’s anchors, etc. It offers a secure alternative route to the land based routes.
■High-capacity, low-latency communications that contribute to supporting high-tech industries and improved quality of consumer businesses
Compared to land based routes, the Tokyo Port route will provide a straight and direct connection between the Toyosu-Ariake and Shibaura-Shinagawa areas, enabling low latency communications. Using the communications services provided by ARTERIA, it is easy to connect to the Chiba Minamiboso area and the North Ibaraki area, where landing stations (the terminals for major submarine cables) are concentrated, supporting the demand for overseas wide-band, low-latency connectivity.
High-capacity, low-latency communications provide the backbone for cutting-edge technological industries such as autonomous driving, industrial robots, drone delivery, and telehealth services.
Furthermore, in industries where high-capacity communication is essential, such as video streaming and the rapidly growing e-sports gaming sector, low-latency network procurement is in constant demand. This new route will enhance the overall quality and user satisfaction of services offered by these industries.
1 According to ARTERIA Networks (as of December 2023)
2 The HDD Method (Horizontal Directional Drilling) is a propulsion technique that applies technology originally used in oil drilling. It minimizes excavation from the surface and advances a drilling machine horizontally to install pipelines underground. In this project, the method is being deployed at depths of over 60 meters at maximum in order to avoid disturbing Tokyo Port's breakwater and seawall structures. Conventional propulsion methods are typically limited to approximately 1,000 meters, and for distances beyond that shield methods are used. However, by adopting the HDD method, it becomes possible to carry out propulsion work to traverse the approximately 2,000-meter-wide Tokyo Port section, achieving a short delivery period, low cost, and the shortest route (ultra-low latency).
