JAKARTA, Indonesia—On July 13, 2026, PT Telkom Indonesia (Persero) Tbk said it will expand and upgrade international fiber-optic links and landing facilities across Indonesia to attract new hyperscale data center and AI investment, advancing the country’s goal of becoming a regional digital hub.
The operator said the program will increase capacity on key regional corridors and add route diversity via additional landing points, while reinforcing domestic backbones connecting Jakarta, Batam and other metropolitan areas. Telkom did not disclose investment figures or a detailed timeline, indicating projects will roll out in phases alongside permitting and partner alignment. Its international subsidiary, PT Telekomunikasi Indonesia International (Telin), is expected to play a central role in execution and consortium participation.
Route diversity and lower latency
Telkom’s plan emphasizes dual-homing and geographically separate landings to reduce single points of failure, a priority for data center operators seeking stringent service-level and latency targets. Additional connectivity toward Singapore and broader ASEAN routes, coupled with diversified paths across Sumatra and Java, are intended to shorten round-trip times for AI training clusters and cross-border workloads. The company also signaled support for open, carrier-neutral meet-me environments at landing stations to ease interconnection and accelerate turn-up for new entrants.
Implications for cable and equipment suppliers
For wire and cable stakeholders, Indonesia’s push points to incremental demand for high-fiber-count terrestrial cables, submarine cable segments, repeaters and power-feeding equipment, as well as coherent optics upgrades at 400G/800G on trunk spans. Expanded landing capacity typically drives orders for armored shore-end cables, branching units, cable protection systems and high-availability terrestrial backhaul. On long-haul spans, operators are increasingly evaluating C+L band line systems and spectrum-sharing models to maximize fiber utilization—areas where component suppliers and systems integrators can differentiate with reliability and power efficiency.
Policy alignment will shape timelines
Industry observers note that streamlined seabed permitting, clear cable protection corridors and single-window licensing can materially accelerate build schedules. Indonesia has prioritized digital infrastructure in recent policy discussions, and alignment between central and local authorities will be pivotal to maintaining project cadence and protecting existing routes during construction. Market timing will also hinge on cable-ship availability and coordination with hyperscalers and regional carriers planning new routes or spectrum leases.
What to watch
As details emerge, the sector will look for confirmation of landing locations, specific international corridors to be augmented, target ready-for-service windows and whether Telkom adopts expanded open-access models at landing facilities. For the wire and cable supply chain, early visibility into route engineering and fiber counts will help allocate manufacturing slots, manage raw-material inputs and align testing resources ahead of expected turn-ups.
