Long Island, India: Submarine Cable Landing Point

Long Island is a landing point in India that serves as a terminus for submarine cable connectivity linking the Indian mainland with the Andaman and Nicobar Islands. As an island location in Indian waters, it sits within a domestic cable corridor that provides dedicated undersea communication infrastructure between geographically separated parts of the same country. One submarine cable currently lands at Long Island, connecting it directly to the Indian mainland and forming part of a broader effort to extend reliable connectivity to India's remote island territories.

The single cable serving Long Island is the Chennai-Andaman & Nicobar Islands Cable, an entirely domestic system that links multiple landing points across India. This positions Long Island as a node on an intra-national cable route rather than an intercontinental or international corridor. Despite hosting only one cable, the landing point plays a meaningful role in providing connectivity to an island group that would otherwise rely on satellite or terrestrial alternatives.

Cables Landing at Long Island, India

The Chennai-Andaman & Nicobar Islands Cable (CANI) is a domestic Indian submarine cable system spanning approximately 2,300 kilometres. The system reached ready-for-service status in 2020 and was developed to connect the Andaman and Nicobar Islands with the Indian mainland. All landing points on this cable are located within India, making it a purely intra-national system. Long Island is one of the landing points on this route, which originates from the mainland city of Chennai and extends to various points across the Andaman and Nicobar island chain.

Regional Context

Within India's submarine cable landscape, Long Island sits alongside a range of other landing points that vary considerably in scale. Major hubs such as Mumbai, with 18 cables, and Chennai, with 9 cables, represent the primary international gateways for India's undersea connectivity. Long Island, hosting a single cable, is comparable in scale to other island-serving landing points such as Agatti, Amini, and Andrott, each of which also hosts one cable, reflecting the focused, domestic purpose these locations serve within India's broader 26-landing-point submarine cable network.

Network Role

Long Island functions as a single-cable terminus within a domestic Indian submarine cable system, enabling direct undersea connectivity between the Andaman and Nicobar Islands and the Indian mainland. The CANI cable, of which Long Island is a part, represents a dedicated infrastructure solution for island territories that are geographically remote from peninsular India. As a terminus rather than a transit or branching hub, Long Island's role is straightforward: it is the local delivery point for the undersea link that the CANI system provides to this part of the Andaman and Nicobar island group.

In the broader graph of India's submarine cable infrastructure, Long Island illustrates how domestic systems complement international ones, ensuring that remote island communities are served by dedicated undersea routes rather than relying entirely on overland or satellite connectivity from the country's major international landing hubs.
