Iloilo City: Submarine Cable Landing Point

Iloilo City is a highly urbanized city situated on the southeastern coast of the island of Panay in the Western Visayas region of the Philippines. As a landing point on an archipelagic nation that relies heavily on submarine cable infrastructure to connect its many islands, Iloilo City hosts two domestic submarine cables. Both cables serve intra-Philippine connectivity, forming part of the network that links the islands and provinces of the archipelago together.

The two cables landing at Iloilo City are the Philippine Domestic Submarine Cable Network (PDSCN) and the National Digital Transmission Network (NDTN). Both systems connect exclusively to other points within the Philippines, positioning Iloilo City as a node within the country's domestic inter-island cable corridor rather than an international or intercontinental gateway.

Cables Landing at Iloilo City

The Philippine Domestic Submarine Cable Network (PDSCN) is a 2,500 km domestic submarine cable system with a ready-for-service (RFS) date of 2023, currently in draft status. The cable connects multiple landing points within the Philippines, extending the reach of high-capacity domestic connectivity to Iloilo City and other locations across the archipelago.

The National Digital Transmission Network (NDTN) is a 1,400 km domestic submarine cable system that entered service in 1999, also in draft status. Like the PDSCN, it connects exclusively to other Philippine landing points, representing one of the earlier domestic cable deployments in the country and providing a foundational layer of inter-island connectivity to Iloilo City.

Regional Context

Within the Philippine submarine cable landscape, Iloilo City ranks among the mid-tier landing points by cable count. Several peers — including Batangas, Cagayan de Oro, Davao, and Taytay — each host four cables, while Baler and Boracay serve as three-cable landing points. With two cables, Iloilo City sits in the top 82% of the 71 landing points across the Philippines, reflecting a meaningful but not dominant share of the country's distributed cable infrastructure.

Network Role

Iloilo City functions as a domestic inter-island cable terminus, connected to the rest of the Philippine archipelago through two systems spanning a combined 3,900 km. The NDTN, dating to 1999, established an early link for Western Visayas, while the more recent PDSCN, with its 2023 RFS date, represents a newer layer of domestic capacity reaching the city. Iloilo City is a two-cable landing point rather than a multi-cable hub, and both of its cables operate entirely within Philippine waters.

In the broader Philippine submarine cable graph — a network of 26 cables spread across 71 landing points — Iloilo City's role is to extend domestic inter-island connectivity to one of the most populous urban centers in Western Visayas, ensuring that Panay island maintains a presence within the country's submarine cable fabric.
