Pasacao, Philippines

Pasacao: Submarine Cable Landing Point

Pasacao is a municipality in Camarines Sur province, on the coast of the Philippines. As a submarine cable landing point, it connects to two domestic submarine cable systems, both of which link various points within the Philippine archipelago. Because both cables serve exclusively domestic endpoints, Pasacao functions as a node within the Philippines' internal inter-island connectivity network rather than as a gateway for international or intercontinental traffic.

The two cables landing at Pasacao — the Philippine Domestic Submarine Cable Network (PDSCN) and the Converge Domestic Submarine Cable Network (CDSCN) — together represent a combined route length of approximately 3,800 kilometres of undersea fiber infrastructure dedicated to domestic service. This pairing positions Pasacao as a meaningful contributor to the Philippines' internal submarine cable map, which spans 26 cables across 71 landing points nationwide.

Cables Landing at Pasacao

Philippine Domestic Submarine Cable Network (PDSCN) is a domestic submarine cable system with a total length of 2,500 kilometres. It reached ready-for-service (RFS) status in 2023 and connects multiple landing points within the Philippines. Pasacao is one of the terminals on this network, which operates entirely within Philippine territory.

Converge Domestic Submarine Cable Network (CDSCN) is a domestic submarine cable system stretching 1,300 kilometres, with an RFS year of 2021. Like the PDSCN, all endpoints on this cable are located within the Philippines. The CDSCN predates the PDSCN by two years and represents an earlier expansion of domestic undersea connectivity to Pasacao.

Regional Context

Within the Philippines' 71 submarine cable landing points, Pasacao hosts two cables, placing it in the top 82 percent of landing points by cable count. Several other Philippine landing points — including Batangas, Cagayan de Oro, Davao, and Taytay — each serve four cables, while Baler and Boracay each serve three. Pasacao's two cables reflect a focused domestic role rather than the broader multi-cable connectivity seen at the country's busiest landing points.

Network Role

Pasacao serves as a two-cable domestic landing point, enabling inter-island submarine connectivity within the Philippine archipelago through both the PDSCN and CDSCN systems. Both cables are oriented entirely toward domestic routing, meaning Pasacao contributes to bridging the many islands of the Philippines rather than to any international submarine corridor. The CDSCN, operational since 2021, and the PDSCN, active since 2023, give this municipality two independent subsea paths for domestic data traffic.

Within the broader Philippine submarine cable graph — which first recorded a landing in 1997 and now encompasses 26 cables — Pasacao represents a domestically focused two-cable hub that reflects the continued buildout of intra-archipelago connectivity in provinces such as Camarines Sur.
