Pinamalayan: Submarine Cable Landing Point

Pinamalayan is a municipality in Oriental Mindoro province in the Philippines, situated along the coast of one of the country's island groups. As a submarine cable landing point, it connects to the national domestic cable network, with three submarine cables making landfall here. All three cables form part of the Philippines' intra-national connectivity infrastructure, linking various points across the Philippine archipelago rather than reaching international destinations.

The three cables landing at Pinamalayan — the PLDT Domestic Fiber Optic Network (DFON), the Philippine Domestic Submarine Cable Network (PDSCN), and the Submarine Cable in the Philippines (SCiP) — collectively represent a concentration of domestic inter-island connectivity. This places Pinamalayan among the more connected landing points in the country, enabling data and communications traffic to flow between different Philippine islands through submarine infrastructure.

Cables Landing at Pinamalayan

The PLDT Domestic Fiber Optic Network (DFON) is a domestic Philippine submarine cable system spanning 11,100 kilometres, the longest of the three cables landing at Pinamalayan. It reached ready-for-service (RFS) status in 1997, making it one of the earliest submarine cable systems to land in the Philippines. The cable connects multiple landing points across the Philippines, forming an extensive inter-island fiber optic network.

The Philippine Domestic Submarine Cable Network (PDSCN) spans 2,500 kilometres and reached RFS in 2023, making it the most recently completed of the three cables at this landing point. Like the DFON, it connects landing points entirely within the Philippines, providing domestic inter-island connectivity across the archipelago.

The Submarine Cable in the Philippines (SCiP) measures 1,638 kilometres in length and achieved RFS in 2022. It is the shortest of the three cables landing at Pinamalayan and, similarly, connects points exclusively within the Philippines. Together with PDSCN, SCiP represents the newer generation of domestic submarine infrastructure at this landing point.

Regional Context

Within the Philippines' 71 submarine cable landing points, Pinamalayan ranks in the top 94 percent by cable count with its three cables. It is matched in cable count by Baler and Boracay, while landing points such as Batangas, Cagayan de Oro, Davao, and Taytay each host four cables, placing them a step above Pinamalayan in terms of concentration of submarine connectivity.

Network Role

Pinamalayan functions as a domestic inter-island hub within the Philippine submarine cable network. All three cables landing here — DFON, PDSCN, and SCiP — connect exclusively to other Philippine landing points, meaning the infrastructure at Pinamalayan is oriented entirely toward intra-national connectivity across the archipelago. The combination of an older cable from 1997 alongside two systems completed in 2022 and 2023 gives this landing point a layered infrastructure spanning different generations of domestic submarine technology.

As a three-cable landing point in a national network that spans 71 landing points and 26 total cable systems, Pinamalayan contributes meaningfully to the redundancy and distribution of domestic submarine capacity across the Philippines, helping to ensure that inter-island connectivity is not concentrated at only a small number of nodes.
