[Tianjin, China], 19th September, 2025 - HMN Tech is pleased to announce the successful completion of marine surveys for Trans Global Cable System (TGCS), invested by PT Trans Indonesia Superkoridor. As a critical national backbone network, the approximately 1,200km system will link Jakarta and Batam, significantly advancing digital connectivity across Indonesia. With the growing demand driven by AI, cloud computing and next-generation mobile networks, the requirement for ultra-high-capacity transoceanic submarine cable systems continues to increase. The TGCS project represents a major technological advancement in international communications. As Asia's first 24FP repeatered submarine network, it is capable of reaching a maximum capacity exceeding 700Tbps, delivering superior performance and high reliability.
Route Map of TGCS Project
The marine survey serves as a critical foundational step for the end-to-end delivery of transoceanic communication networks. Data collected on seafloor topography, geomorphology, sediment stratification with mechanical properties during the survey provides essential insights for cable type selection, installation solution, and system protection design, which lays a solid groundwork for efficient construction and long-term system reliability.
Marine Survey of TGCS Project
The TGCS project incorporates the latest advancements in submarine network technology. Based on the well-proven platform of HMN Tech SDM Repeater that supports a maximum of 32FP, this project is equipped with customized 24FP Repeater, which is capable of reaching a maximum capacity exceeding 700Tbps. The robust network effectively satisfies the growing bandwidth demands driven by digital transformation and AI applications. Furthermore, the system is equipped with leading-edge Branching Unit featuring 18kV hot switch functionality, significantly enhancing operational safety and maintenance efficiency. Designed with future expansion, the network allows for future extension toward Ketapang, Kalimantan, offering enhanced flexibility to support Indonesia’s evolving communications infrastructure.
HMN Tech provides end-to-end customized submarine cable solutions. Industry-leading Open Cable technology enables spectrum sharing, facilitating multi-operator connectivity and significantly improving the flexibility and scalability of network access. Through professional network design and highly reliable product architectures, the system achieves transmission latency as low as 12ms, ensuring high-speed and stable connectivity across Indonesia.
Scheduled for commercial use in the fourth quarter of 2026, the TGCS project will substantially boost communication quality and capacity between key Indonesian regions while strengthening digital resilience across Asia.
Revolin Nasution, President Director of PT Trans Indonesia Superkoridor, emphasized the profound significance of the project: "We are delighted to launch the TGCS project, which represents a major leap forward in Indonesia’s digital infrastructure. This system will provide ultra-high capacity and high scalability network services, serving as a crucial driver for regional development."
Ma Yanfeng, Executive Vice President of HMN Tech, commented, “We are honored to collaborate with PT Trans Indonesia Superkoridor on this strategically significant backbone network. Asia's first 24FP repeatered submarine network will deliver massive capacity and high reliability, strengthening regional digital connectivity and resilience in the intelligent era.”
