The Barat Timur Indonesia (BTI) cable system links Batam, Jakarta, and Manado, including seven cable landing stations, with a cable length of more than 4,700 kilometers.

The BTI cable system is owned and operated by Super Sistem Group, an Indonesian operator founded in Jakarta in 2013.

In July 2023, the U.S. Trade and Development Agency (USTDA) awarded a grant of US$1.4 million to PT Super Sistem Data (Super Sistem) for a feasibility study to support the development of a domestic subsea fiber optic cable system, the Barat Timur Indonesia (BTI) cable system. Super Sistem selected Florida-based APTelecom to conduct the study. 

USTDA’s support for the BTI subsea cable project advances the Partnership for Global Infrastructure and Investment (PGII) and the Indo-Pacific Economic Framework (IPEF), with the goal of developing, expanding, and deploying secure digital infrastructure to power economic growth and facilitate open digital societies.

In May 2024, Super Sistem selected Infinera’s GX Series and ICE6 800G coherent solution to power the Super Sistem Batam Singapore (SSBS) cable system connecting Batam to Singapore. The SSBS cable system forms part of Super Sistem’s broader national initiative, the Barat Timur Indonesia (BTI) cable system.

The BTI/SSBS cable system is expected to be ready for service in 2026.
