Sriracha, Thailand: Submarine Cable Landing Point

Sriracha is a coastal town in Thailand that serves as a submarine cable landing point on the country's eastern Gulf of Thailand shoreline. Four submarine cables land at Sriracha, making it one of the more active landing points in the country. Among these, the Asia-America Gateway (AAG) Cable System and the Asia Direct Cable (ADC) stand out as the two intercontinental systems, connecting Thailand to destinations across Southeast Asia and beyond.

The combination of cables landing at Sriracha enables two distinct connectivity corridors. The international systems — AAG and ADC — link Thailand into a broad regional and trans-Pacific network spanning countries including China, Japan, the Philippines, Singapore, Malaysia, Vietnam, Brunei, and Guam. The two domestic systems — CSN and TDSCN — connect Sriracha to other landing points within Thailand itself, forming part of the country's internal submarine cable infrastructure.

Cables Landing at Sriracha

The Asia-America Gateway (AAG) Cable System is a 20,000 km cable that entered service in 2009. In addition to Thailand, it connects Brunei, China, Guam, Malaysia, the Philippines, and Singapore, forming one of the major submarine cable routes linking Southeast Asia to the broader Asia-Pacific region.

The Asia Direct Cable (ADC) spans 9,988 km and reached ready-for-service status in 2024. It connects Sriracha to China, Japan, the Philippines, Singapore, and Vietnam, representing one of the most recently activated international cable systems at this landing point.

The CAT Submarine Network (CSN) is a 1,240 km cable that entered service in 2013. Its other endpoints are located within Thailand, making it a domestic submarine cable serving the country's internal connectivity needs.

The Thailand Domestic Submarine Cable Network (TDSCN) is an 884 km cable that has been in service since 2001. Like CSN, its other endpoints are located entirely within Thailand, making it the older of the two domestic systems at this landing point.

Regional Context

Within Thailand's seven submarine cable landing points, Sriracha ranks among the more connected, hosting four of the country's sixteen submarine cables. Songkhla leads the country with nine cables and Satun follows with seven, while Chumphon, Koh Samui, Phetchaburi, and Rayong each host a single cable. Sriracha's four cables place it in the upper tier of Thai landing points by cable count.

Network Role

Sriracha functions as a multi-cable landing point supporting both international and domestic submarine cable connectivity. Its two international cables — AAG, active since 2009, and ADC, active since 2024 — collectively reach eight other countries across Southeast Asia and the broader Pacific, while its two domestic cables extend its role into Thailand's internal submarine cable network. The pairing of an older international system with a newly activated one means Sriracha carries cable infrastructure spanning more than two decades of deployment.

The presence of four cables across both international and domestic categories gives Sriracha a compound role in the Thai submarine cable graph, serving as a node in both the country's external connectivity and its intra-national cable architecture.
