Jakarta, INTI - Indonet has officially activated its third underground fiber optic route connecting Jakarta with industrial areas and data center hubs across Bekasi and Karawang. The new infrastructure forms part of the company's East Route expansion, designed to strengthen Indonesia's digital connectivity and support the rapid growth of the country's data center ecosystem.
The latest route spans more than 80 kilometers and offers a capacity of 2 × 576 fiber cores. The first two routes have been operational since 2025. With the launch of the third route, Indonet's total fiber optic network now reaches approximately 850 kilometers, representing a 141% increase compared with its network capacity before 2024.
The additional network capacity is expected to enhance service performance and strengthen data center interconnection for customers requiring high availability, reliability, and business continuity.
Indonet stated that it is among the first digital infrastructure providers in Indonesia to develop a fully underground fiber optic corridor connecting central Jakarta with industrial zones and data center facilities in Bekasi and Karawang.
Beyond network expansion, the company has also upgraded its backbone network capacity to 100 Gbps to support increasing connectivity demands in developing industrial areas, including the Mitra Karawang Industrial Estate (KIM).
Indonet President Director Donauly Situmorang said that connectivity infrastructure has become a critical foundation amid rising investments in data centers, cloud computing, and artificial intelligence (AI).
"Indonesia is entering a new phase of digital infrastructure development. Investments in data centers, cloud, and AI will continue to grow, but the value of these investments can only be fully realized when supported by equally strong connectivity infrastructure. Therefore, we continue investing in underground fiber optic networks and reliable data center interconnection infrastructure," Donauly said.
He added that the expanded network will allow businesses to scale their operations with greater confidence without being limited by digital infrastructure constraints.
Improving Network Reliability
Indonet Operations Director Agus Ariyanto explained that underground fiber optic networks were selected due to their higher reliability compared with aerial fiber networks.
The cables are installed approximately 1.5 to 2 meters underground, providing greater protection against external risks such as extreme weather conditions and construction activities.
"This infrastructure enables us to deliver more stable connectivity, strengthen network redundancy, and ensure reliable services for mission-critical connectivity requirements," Agus said.
According to the company, these capabilities are essential for supporting business applications such as disaster recovery systems and AI workloads that require consistent network performance.
Data Center Growth Drives Interconnection Demand
Indonesia's rapidly expanding data center industry is increasing demand for high-capacity digital interconnection infrastructure.
According to the Indonesia Data Center Market Share Analysis, Industry Trends & Statistics, Growth Forecasts (2026–2031) report published by Globe Newswire, Indonesia's data center market is projected to grow from approximately US$1.83 billion in 2026 to US$3.48 billion by 2031, representing a compound annual growth rate (CAGR) of 13.71%.
Indonet Sales & Marketing Director Yudie Haryanto said that this growth is not only increasing computing capacity requirements but also driving demand for fast, secure, and sustainable connectivity between data centers.
"High-quality interconnection plays an important role in maintaining application performance, ensuring service continuity, and enabling low-latency data exchange. Through underground fiber optic expansion and increased backbone capacity, we are providing reliable, scalable infrastructure to support our customers' business growth," Yudie said.
The strengthened network is also expected to support Indonesia's national data center ecosystem, including the 500 MW data center campus in Bekasi being developed by Digital Edge Indonesia. The integration of advanced connectivity infrastructure with large-scale data center facilities is expected to accelerate the growth of AI services, cloud platforms, and Indonesia's digital economy.
Conclusion
Indonet’s new underground fiber optic route strengthens Indonesia’s digital infrastructure by improving connectivity between Jakarta, Bekasi, and Karawang. The expansion supports growing demand from data centers, cloud services, and AI workloads while enhancing network reliability for Indonesia’s digital economy.
