The Philippines is uniquely dependent on submarine cables because of its geography.
The Philippines is preparing to make one of its most ambitious bets yet on digital infrastructure, with the country’s three largest broadband providers joining forces on a proposed $500 million national submarine cable system. The project could do far more than improve internet speeds. It has the potential to create a new infrastructure market spanning telecommunications, data centres, cloud computing, artificial intelligence, disaster resilience and national security.
PLDT, Globe Telecom and Converge ICT Solutions have presented the proposal to the Department of Information and Communications Technology (DICT), with the companies expected to finance the project themselves. If approved, construction is targeted for completion within 24 months. The preliminary route would begin in Batanes, move towards Palawan, connect the Visayas and extend into Mindanao, creating a large loop designed to provide greater network redundancy. The significance lies in the fact that this is not simply another broadband upgrade. The proposed system would establish a new national layer of digital infrastructure at a time when the Philippines is attempting to position itself as a regional destination for data centres, cloud services, AI and other technology-intensive industries.
The Philippines is uniquely dependent on submarine cables because of its geography. With thousands of islands spread across a large maritime area, extending terrestrial fibre everywhere can be expensive, slow and technically difficult. The new proposal therefore reflects a practical shift towards using the sea as the country’s digital highway. DICT Secretary Henry Aguda has said the proposed cable will not merely carry internet traffic. It is also expected to incorporate Digital Acoustic Sensing technology, potentially allowing the cable network to detect seismic activity, tsunamis and even vessels moving above the cable. That would give a telecommunications asset additional value for disaster preparedness and maritime monitoring.
The timing is particularly significant. In June 2026, the Philippines experienced a magnitude 7.8 earthquake offshore of Sarangani, with tsunami waves recorded along parts of the southern coastline. The event underlined the importance of resilient communications and early-warning capabilities in a country exposed to earthquakes, typhoons and other natural hazards. Globally, the strategic importance of subsea infrastructure is also becoming clearer. The International Telecommunication Union says submarine cables carry more than 99 per cent of the world’s data traffic and warns that physical damage and geographical concentration can create major economic and security vulnerabilities. For the Philippines, building additional routes is therefore becoming an economic necessity rather than a luxury.
The most important consequence of the $500 million proposal could be what develops around it. A submarine cable requires landing stations, fibre backhaul, network equipment, maintenance services, power infrastructure, cybersecurity systems and specialised engineering. Once those assets are in place, they can attract businesses that require reliable, high-capacity connectivity. That is already beginning to happen. In March, InfiniVAN announced a $31 million investment in a cable landing station in Baler, Aurora, including expansion of the facility. The station forms part of the 8,000-kilometre Candle submarine cable system connecting Japan, Taiwan, the Philippines, Indonesia, Malaysia and Singapore.
Globe has also joined the Candle consortium as an investor and landing party. Its Nasugbu Cable Landing Station in Batangas will complement the Baler landing, creating connectivity on both the eastern and western sides of the country. The system is expected to enter service in 2028 and will use 24 fibre pairs, targeting the growing requirements of cloud computing, AI and enterprise digitalisation. This is important because the Philippines is beginning to move from being simply a consumer of international bandwidth to becoming a location where digital infrastructure can be developed, interconnected and commercialised.
Subsea cables and data centres are increasingly becoming two sides of the same investment equation. A data centre without abundant, resilient international connectivity is commercially constrained. Equally, a cable landing station becomes more valuable when cloud providers, enterprises and data centres are located nearby. The Philippines is already targeting this opportunity. In January, President Ferdinand Marcos Jr. discussed a planned DAMAC Digital data centre investment in Laguna and highlighted the country’s ambitions to become a regional hub for data centres, cloud services and AI-driven technologies.
The government’s investment strategy is also becoming more supportive. Its 2026 Strategic Investment Priority Plan identifies data-centre facilities, artificial intelligence and cybersecurity among activities critical to structural economic transformation. The commercial opportunity could therefore extend well beyond the cable itself. New landing stations can encourage the development of carrier-neutral facilities, edge computing sites, cloud connectivity hubs and data centres. Telecommunications operators, infrastructure funds, engineering companies, energy providers and technology firms could all participate in the emerging ecosystem.
One of the most interesting developments is the growing importance of locations outside Metro Manila. BCDA and InfiniVAN have agreed to develop the Poro Point Cable Landing Station in La Union as an open gateway for international submarine cables. The agreement also covers part of a 240-kilometre fibre-optic conduit network connecting Poro Point and Baler. Meanwhile, APECO and InfiniVAN are exploring terrestrial connectivity linking the Aurora economic zone with submarine cable capacity in Baler, Claveria and other emerging northern Luzon landing corridors. APECO has explicitly positioned the area as a potential data-centre hub.
This could gradually change the geography of the Philippine digital economy. Instead of concentrating connectivity and data infrastructure almost entirely around Manila, new cable routes could allow secondary cities and economic zones to compete for digital investment. That matters for property development, power generation, industrial parks and regional employment as much as it does for telecommunications.
Perhaps the most striking aspect of the $500 million proposal is that PLDT, Globe and Converge are competitors. Their decision to collaborate on a shared national infrastructure project shows how strategically important connectivity has become. The investment is also notable because the government would not have to shoulder the estimated $500 million cost. The telecom companies have indicated that the consortium would finance the project itself.
For investors, this creates an encouraging signal. Private capital is increasingly prepared to fund infrastructure when demand for bandwidth, cloud services and digital applications is sufficiently strong. The government is simultaneously trying to create the policy environment needed to support that investment. In January, the National Digital Connectivity Plan was approved with objectives including greater infrastructure investment through public-private partnerships, wider connectivity and more resilient, climate- and disaster-proof digital assets.
The Philippines cannot afford to treat subsea connectivity simply as a capacity race. Natural disasters represent a persistent threat. Typhoons, earthquakes, underwater landslides and other hazards can damage cables and disrupt communications. Internationally, the ITU reported more than 170 submarine cable repairs in 2025, demonstrating how frequently these networks can be affected. That makes route diversity increasingly valuable.
The combination of the proposed national cable, the Candle system, new landing stations and the government’s Luzon Bypass Infrastructure could create multiple pathways into and across the Philippines. Such redundancy can reduce dependence on individual routes and help businesses maintain operations when one connection is disrupted. For multinational companies considering the Philippines for cloud operations, business-process services or AI workloads, that resilience could become a genuine investment advantage.
