Shoreham, NY: Submarine Cable Landing Point

Shoreham is an incorporated village in the Town of Brookhaven, Suffolk County, on the north shore of Long Island, New York, United States. Despite its modest size — with a population of 561 recorded at the 2020 census — Shoreham serves as a submarine cable landing point on the eastern seaboard of the United States. One submarine cable makes landfall here, connecting Shoreham to another point within the United States in a domestic inter-state corridor.

The single cable landing at Shoreham is the Cross Sound Cable, a relatively short domestic link that, by its name and routing, bridges the Long Island Sound. This positions Shoreham as a terminus in a regional, intra-national submarine connection rather than an intercontinental gateway.

Cables Landing at Shoreham, NY

Cross Sound Cable is a 40-kilometre submarine cable that reached ready-for-service status in 2003. It connects two points within the United States, linking Shoreham on Long Island's north shore to another landing point across the Long Island Sound. At just 40 kilometres, the Cross Sound Cable is a short-haul domestic link, designed to span the Sound rather than cross ocean basins. It remains the sole submarine cable serving the Shoreham landing point.

Regional Context

Within the United States submarine cable landscape — which encompasses 113 cables across 160 landing points — Shoreham hosts a single cable and ranks in the top 69 percent of domestic landing points by cable count. Compared to high-density hubs such as Boca Raton, FL, and San Juan, PR (each serving eight cables), or Hermosa Beach, CA, and Kapolei, HI (each serving five), Shoreham represents a more specialised, single-purpose landing point focused on a specific domestic corridor rather than a convergence of international routes.

Network Role

Shoreham functions as a single-cable terminus, hosting only the Cross Sound Cable and enabling domestic submarine connectivity across the Long Island Sound. Its role is distinctly regional in character: rather than aggregating traffic from multiple international cable systems, it supports a focused point-to-point link between two locations within the United States. This makes Shoreham a specialised node rather than a multi-cable hub in the broader national submarine cable network.

In the wider graph of United States submarine cable infrastructure, Shoreham's presence illustrates how submarine technology is applied not only to transoceanic routes but also to short domestic crossings where overland or overhead alternatives may be less practical. Its position on Long Island's north shore, facing the Sound, reflects the geographic logic that drives the placement of domestic submarine cable landings.
