NTT Com launches lower latency service between JPX and SGX

NTT Communications, the international communications business of NTT Group, has added a new ultra-low-latency connectivity service between two of Asia’s premier stock exchanges, the Japan Exchange Group (JPX) and Singapore Exchange (SGX).

This new connectivity service will offer the telecom industry’s lowest latency route for international leased lines between the two colocation facilities – with an unmatched latency of 63.5ms.

This new service connects Access Point 3 of JPX, where many financial institutions have their servers, to SGX’s data centre. Lower latency services enable investors trading at JPX and SGX to improve the agility of their high-frequency trading operations and strengthen their competitiveness.

NTT Com launched the JPX-SGX Co-Location Direct service in April 2015, to provide the lowest-level latency between JPX and SGX at 63.7ms. The service exploits the company's Asia Submarine Cable Express (ASE), which takes the shortest cable route between Japan and Singapore.

The new service decreases latency even further by adding an NTT Com point of presence (PoP) at Access Point 3 of JPX in a more advantageous location that connects to the landing station via the shortest possible route. Additionally, since the new PoP is directly connected to the structured cable, an external connection is no longer needed, ultimately reducing the lead time.

NTT Com says it plans to implement further measures in March 2016 that will shave even more time from the latency.

The latency of the service is given as a round-trip latency measured using a 1Gb/s test cable and 1000Base-LX/64-bite packet environment. NTT Com notes that the actual latency may vary depending on network environment.

NTT Com's JPX-SGX Co-Location Direct provides cost savings and low-latency connectivity for customers using "JPX Co-Location Service (all)", which is offered by JPX. The new ultra-low-latency option will be available not just for those customers but also for those using other colocation and connectivity services.
