The Shift in Physical Capacity
September 11, 2026. In Tanjung Bemban, on the island of Batam in Indonesia, a golden milestone marks the landing of the first section of the CANDLE Cable System. This event is not symbolic: it initiates the laying of an underwater backbone exactly 8,000 kilometers long that will directly connect Indonesia, Singapore, Malaysia, the Philippines, Taiwan, and Japan. The date sets a point of no return in regional digital infrastructure.
The project, developed by PT XLSMART Telecom Sejahtera Tbk (XLSmart), responds to a real physical pressure: the saturation of terrestrial connections and existing routes towards data processing centers. Commercialization is expected in 2028. Within this timeframe, the capacity for data transport will definitively shift from land to the depths of the sea, reducing dependence on traditional terrestrial nodes.
The route selection is not random. By connecting Batam to Singapore and then branching northeast towards Asia, the cable avoids infrastructure bottlenecks that characterize terrestrial networks. Physical latency is reduced because light travels faster in underwater glass than through crowded terrestrial repeaters.
Node Engineering and Technical Constraints
The technical realization of the CANDLE Cable System relies on a specific industrial partnership. NEC Corporation, the Japanese technology partner, provides the engineering standards for deep-water laying. The complexity does not lie in the optical fiber itself, but in the submarine repeaters that amplify the signal every 49 to 49 miles (80 to 113 kilometers).
The main operational constraint is the laying time and the oceanographic conditions of the Strait of Malacca and the Philippine Sea. The currents and depth require specialized cable-laying ships, a scarce global resource. The operating window to complete 5,000 miles (8,000 kilometers) by 2028 is tight but technically feasible with the current fleet.
The choice of Batam as a strategic landing point leverages its proximity to Singapore, the main data hub in Asia. This creates a ring of resilience: if a terrestrial cable fails, traffic can be routed via sea without passing through congested terrestrial gateways.
Mapping the Actors and Costs
The project’s financiers define the actual demand. Meta, Globe Telecom, Telekom Malaysia, SoftBank, and IPS Inc. are the key investors. Their presence indicates that the generated traffic will be primarily cloud computing and artificial intelligence, not just consumer connectivity.
SoftBank, with its data centers in Japan and Taiwan, directly benefits from the reduced cost of transferring data to Indonesia. Meta, with its hubs in Singapore, gains a critical backup capacity for Southeast Asia.
The construction costs are high but amortized over decades. The real savings are operational: less maintenance on terrestrial cables, lower risk of interruptions due to excavations or terrestrial weather events. Resilience is bought with the initial capital expenditure (CAPEX).
Trajectory and Structural Limits
The CANDLE Cable System is not just a cable: it’s a national digital security infrastructure for the countries involved. For Indonesia, it means greater control over its own data flows. For Japan, it guarantees access to emerging Southeast Asian markets.
The measurable impact will be a reduction in latency between Jakarta and Tokyo of approximately 10-15 milliseconds compared to current terrestrial routes. This improvement is crucial for financial applications and cloud gaming.
The structural limit is the dependence on NEC technology and repeater suppliers. If a failure occurs at a depth of 4,000 kilometers, repair times are weeks, not days. Physical resilience comes at a price in terms of recovery time.
By 1028, when the cable becomes operational, the Asian data architecture will have irrevocably changed. The demand for submarine capacity will continue to grow, driven by artificial intelligence. The CANDLE Cable System is the first of a new generation of backbones that prioritize physical speed over terrestrial flexibility.
