PT Indointernet Tbk. (Indonet) has launched the third route of its underground fiber optic network to strengthen connectivity reliability for industrial facilities and data centers across the Bekasi–Karawang corridor.
With the addition of the third route, the total length of Indonet's underground fiber optic network has increased by approximately 141% compared with its pre-2024 network infrastructure.
Indonet Operations Director Agus Ariyanto said the additional fiber optic infrastructure enhances the performance and resilience of the company's existing transmission system. Ensuring high service availability remains a key priority in supporting today's increasingly hybrid business operations.
"Both underground fiber routes that have been operational since 2025 have maintained 100% Ready for Service (RFS), indicating that there have been no fiber cable disruptions or outages to date," Agus told Bisnis on Wednesday (July 8, 2026).
According to Agus, the network expansion broadens Indonet's coverage while improving overall service reliability. For business-to-business (B2B) customers, the expanded and more resilient network enables the company to deliver more dependable connectivity to support growing business demands, particularly in industrial estates, data centers, and enterprise operations.
Installing the entire fiber optic infrastructure underground is a core component of Indonet's strategy to minimize the risk of physical damage. The approach has proven effective in maintaining stable data transmission since the initial network corridor was introduced.
Agus added that implementing route diversity through three separate fiber routes with adequate physical separation allows data traffic to be automatically rerouted if one route experiences a disruption. All fiber optic cables are buried at depths ranging from 1.5 to 2 meters and are monitored through routine patrols conducted by the company's operational teams.
In addition to improving physical network resilience, Indonet has designed its infrastructure with substantial capacity to accommodate future growth in digital demand. The company has upgraded its backbone network capacity to 100 Gbps, enabling higher bandwidth to support data-intensive business applications in the Karawang Mitra Industrial Estate (Kawasan Industri Mitra Karawang/KIM).
The company believes significant opportunities remain for digital infrastructure expansion as Indonesia continues to accelerate technology transformation, cloud adoption, and artificial intelligence implementation.
"The deployment of 2 × 576-core fiber is part of Indonet's long-term strategy to anticipate the growing demand for connectivity across industrial estates and data center clusters," Agus said.
