Ratmalana is a suburb located in the Colombo District of Western Province, Sri Lanka, situated approximately 14.6 kilometres south of Colombo city centre along the country's western coastline. As a submarine cable landing point, Ratmalana hosts one international submarine cable, connecting Sri Lanka to a corridor that spans the Bay of Bengal and extends into the broader Indian Ocean region.
The single cable landing at Ratmalana, the Bay of Bengal Gateway (BBG), links Sri Lanka westward toward Oman and the United Arab Emirates and eastward toward India and Malaysia. This positions Ratmalana as a landing point on an intercontinental route connecting South Asia, Southeast Asia, and the Middle East within a single cable system.
The Bay of Bengal Gateway (BBG) is an 8,100-kilometre submarine cable system that entered service in 2016. In addition to Ratmalana, the BBG lands in India, Malaysia, Oman, and the United Arab Emirates. The cable spans the Bay of Bengal and the Arabian Sea, forming a link between Southeast Asian connectivity hubs in Malaysia, the South Asian landmass through India and Sri Lanka, and the Gulf region via Oman and the UAE. Ratmalana represents the Sri Lankan terminus of this system.
Within Sri Lanka's submarine cable infrastructure — which comprises nine cables distributed across four landing points — Ratmalana hosts one cable, placing it among the less densely served landing points alongside Mt. Lavinia, which hosts two cables. Colombo and Matara each serve three cables, making them the most cable-rich landing points in the country. Ratmalana's single-cable profile positions it as a specialised terminus rather than a multi-cable aggregation point within the national network.
Ratmalana functions as a single-cable terminus on the Bay of Bengal Gateway system, providing Sri Lanka with a direct link into a five-country cable network extending from Southeast Asia through South Asia and into the Gulf. The BBG's routing through Ratmalana means the landing point participates in an intercontinental corridor connecting Malaysia, India, Sri Lanka, Oman, and the United Arab Emirates — a span that crosses two major maritime regions, the Bay of Bengal and the Arabian Sea.
As one of four submarine cable landing points in Sri Lanka, Ratmalana contributes to the geographic distribution of the country's undersea cable infrastructure along the western coast. Its place in the regional submarine cable graph reflects Sri Lanka's role as a waypoint on Indian Ocean routes that bridge the Gulf and Southeast Asia.
