Digital Realty yesterday announced a partnership with BW Digital to jointly support the rollout of BW Digital’s Nongsa Changi Cable System (NCC), a new submarine system designed to connect Batam in Indonesia with Singapore. The firm, in a press release added that it is also overseeing its integration with Digital Realty’s SIN12 data centre on the island state. SIN12 is able to support high-performance workloads at scale, as well as providing access to vital cloud and connectivity hubs, particularly for enterprises expanding across Southeast Asia. This helps to strengthen cross-border connectivity, storage and compute, while at the same time supporting Singapore’s accelerating AI and digital transformation demands.
By landing NCC in SIN12, both parties hope to deliver faster, more reliable, and more sustainable data exchange between Singapore and Batam. As the first submarine cable to land directly in Nongsa Digital Park, NCC is designed to deliver more than 1.6 petabits per second (Pb/s) of new capacity and provide seamless DC-to-DC connectivity with less than 2 milliseconds (ms) latency to Singapore.
The collaboration is designed to integrate submarine cable landing facilities with Digital Realty’s global data centre platform This could hopefully enable high-performance subsea connectivity, storage and interconnection within SIN12 and Artificial Intelligence/Machine Learning (AI/ML) computing enablement via PlatformDIGITAL®.
BW Digital’s in-progress NDP-1 data centre in Batam is planned to further support Digital Realty’s customers. Dubbed an ‘AI Factory’, NDP1 data centre, with a capacity of 144MW and liquid cooling capabilities, is designed to feature direct on-ramps to BW Digital’s subsea cable landing station for low-latency and resilient links to regional markets.
At the signing ceremony in Singapore yesterday, Serene Nah, Managing Director and Head of Asia Pacific, Digital Realty, said: “Subsea networks are central to Southeast Asia’s digital economy, and Singapore continues to serve as a critical gateway for regional data exchange. By integrating BW Digital’s Nongsa–Changi system into SIN12, we are working to deliver faster and more resilient connectivity to support customers as they scale next-generation workloads.”
Virgine Frouin, Chief Business Officer, BW Digital said: “This partnership represents a major milestone for BW Digital, aligning with our mission to support digital transformation by bridging the gap between submarine cable infrastructure and land-based digital platforms in a way that is efficient, secure, and future-ready.”
Headquartered in Singapore and part of BW Group, BW Digital’s main assets include the 15,000km Hawaiki submarine cable connecting Australia, New Zealand and the US since 2018, and the BW Digital Campus at Nongsa Digital Park, comprising the 144MW NDP1 data centre, the NCC submarine cable between Singapore and Batam and the Citra Connect terrestrial fibre network.
