NTT Communications Expands Tokyo Stock Exchange's Global Reach with Arrownet-Global to Singapore

SINGAPORE – 22 May 2013 – Tokyo Stock Exchange (TSE) partners with NTT Communications Corporation to launch its arrownet-Global network service in Singapore. Leveraging NTT Communications’ Ethernet Leased Line service and ultra-low latency cable systems, including the Asia Submarine Cable Express (ASE), the new connectivity offering will enable global financial service institutions in Singapore and Malaysia to directly access JPX Co-location (all), the new co-location service of Japan Exchange (JPX), and TSE’s systems for the first time.

arrownet is a highly reliable low latency network service offered by TSE since 2009 for financial service institutions to connect with its trading and information systems and also co-location racks in Tokyo. With the availability of arrownet-Global, overseas financial institutions can now directly connect to JPX Co-location (all) and TSE’s system, thereby strengthening the exchange’s value proposition while broadening its investor pool.

NTT Communications’ long-term relationship with TSE, wide network infrastructure and established track record are key reasons for its selection by TSE as the exchange’s first partner in launching arrownet-Global. In addition, the availability of this service over the ultra-low latency ASE that bypasses major seismic locations offers additional assurance in meeting the demand for reliable services.

Mr. Yoshinori Suzuki, Senior Managing Director of Tokyo Stock Exchange commented, “arrownet-Global enables the global investors in Asia and across the world to access the JPX market from outside of Japan more easily and effectively by realizing a seamless connection with arrownet via NTT Communications’ wide global coverage. I hope that straightforward access to the JPX market will strengthen the value of TSE’s IT infrastructure and boost the liquidity of the JPX market, so that JPX can achieve its corporate aim to become ‘the Most Preferred Exchange in the Asian Region’.”

NTT Communications provides end-to-end network solution with its Ethernet Leased Line service, which connects the clients’ systems in Singapore all the way through to JPX Co-location and TSE’s system in Tokyo. Clients will be able to enjoy one-stop services from ordering to network infrastructure design and maintenance with NTT Communications as the single contact point.

The service will ride on NTT Communications’ ASE cable system that connects key financial hubs in Asia through the shortest possible route. This ASE cable system boasts industry leading network latency of less than 64milliseconds from Singapore to Tokyo.   Clients can enjoy optimized latency by co-locating their systems at Singapore Serangoon Data Center, where the ASE cable system is directly connected to NTT Communications' global network infrastructure.

“Low latency and reliable network are crucial to the success of financial services industry clients. Our partnership with TSE and the launch of arrownet-Global are some of the initiatives to ensure that our clients enjoy the lowest latency, highest reliability and capacity. It further affirms our leadership in networking and one-stop solution approach to global connectivity.” said Mr Takeshi Kazami, President and CEO
