PT Telekomunikasi Indonesia International (Telin) and Singtel announced that they have signed a Memorandum of Understanding to develop a new submarine cable system connecting Singapore and Batam, Indonesia, under the newly formed INSICA (Indonesia Singapore Cable System) Consortium. When operational in the fourth quarter of 2026, the 100-km INSICA cable system will support the surge in data center telecommunications traffic between Singapore and Batam. INSICA will feature a 24-fiber pair subsea cable and two diverse terrestrial cable paths, offering a maximum capacity of up to 20 terabits per second per fiber pair.

This will deliver exceptional bandwidth, seamless connectivity and robust network security and enable efficient resource sharing and scalability. The new diverse link provided by INSICA will enhance network protection and reliability, ensuring uninterrupted 24/7 operations for data centers. The direct connectivity between data centers will also support the deployment of emerging technologies, such as the Internet of Things, robotics, AI and data analytics, all of which require high bandwidth and low latency for commercial-scale and real-time applications.

Southeast Asia's data center sector is experiencing rapid growth, driven by advances in AI, cloud computing, e-commerce, IoT, edge computing, and 5G. This growth is attracting a wave of investment from both established players and new entrants.
