Singapore is a truly hub for global telecommunications and submarine networks in APAC region. Singapore is the most-connected country in Asia from number of landed cables, even more than those in Japan and India.

The Info-communications Media Development Authority (IMDA) is the lead agency for facilitating the deployment of submarine cable systems into Singapore. The IMDA provides guidance to interested parties and facilitates the process for applying for the necessary permits from various authorities. a Facilities-Based Operations (FBO) licence is required to deploy the submarine cable system into Singapore.

According to the 2016 edition of the Guidelines on Deployment of Submarine Cables into Singpaore issued by IMDA, as of September 2016, Singapore is connected to 17 active submarine cable systems, with a potential bandwidth capacity of more than 410 Tbps. These 17 submarine cable systems are landed in three designated landing sites in Singapore, namely the Changi North landing site, the Tanah Merah landing site, and the Tuas landing site. All new submarine cable systems can only be deployed to designated landing sites and each landing site is available on a first-come-first-served basis. 

There are now seven cable landing stations in Singapore, including:

Here is a complete list of submarine cables connecting Singapore:

Cables northeastwards to Asia

Cables westwards to South and West Asia

Cables westwards to Europe and Africa (as well as South and West Asia)

  • AAE-1(2017). The AAE-1 doesn't land in Singapore, instead in Malaysia. With terrestrial extension between Malaysia and Singapore as a part of the AAE-1 cable system, AAE-1 Singapore PoPs are located at Equinix and Global Switch data centers in Singapore 
  • SMW3
  • SMW4
  • SMW5 (2016)
  • SMW6 (2023)

Cables eastwards to Australia

Cables connecting the United Station

  • AAG
  • BtoBE (2022 or later)
  • SEA-US (2018). The SEA-US terminates in Kauditan, Indonesia, without landing in Singpaore. Combined with SEA-US, Telin's IGG and other subsea cables, SEA-US forms an importan route connecting Singapore and the US.
