Grand Bahama Bimini Submarine Cable

Overview

The Grand Bahama Bimini Submarine Cable is a regional submarine cable system located in the Bahamas. Spanning a length of 117 kilometers, it connects two key points within the archipelago: Alice Town on Bimini and Eight-Mile Rock on Grand Bahama Island. The cable was officially ready for service in 2005 and is owned and operated by the Bahamas Telecommunications Company. As an integral part of the nation's telecommunications infrastructure, it plays a vital role in supporting local connectivity and internet services.

This cable is designed to address the unique challenges posed by the geography of the Bahamas, a nation composed of over 700 islands and cays. Submarine cables are essential for linking communities separated by water, ensuring reliable communication and data transfer across the region. The Grand Bahama Bimini Submarine Cable exemplifies the importance of such systems in maintaining connectivity within island nations.

Route and Landings

The Grand Bahama Bimini Submarine Cable connects Alice Town on Bimini Island to Eight-Mile Rock on Grand Bahama Island. Alice Town, located on the westernmost island of the Bahamas, serves as a gateway to the Gulf Stream and is a hub for tourism and fishing. Eight-Mile Rock, situated on the western edge of Grand Bahama Island, is one of the largest settlements on the island and is known for its residential and commercial significance.

The cable traverses the shallow waters of the Great Bahama Bank, a submerged carbonate platform that dominates the region's seabed. This route avoids deep ocean trenches, making it relatively straightforward for cable installation and maintenance. By linking two major islands, the cable enhances intra-island communication and provides critical infrastructure for businesses, residents, and government entities. Its strategic placement reflects the need to connect population centers and economic hubs within the Bahamas.

Ownership and History

The Grand Bahama Bimini Submarine Cable is owned and operated by the Bahamas Telecommunications Company (BTC). BTC is the primary telecommunications provider in the Bahamas, offering services such as mobile, broadband, and fixed-line connectivity. The cable was completed and made operational in 2005, marking a significant step in the expansion of the country's digital infrastructure.

BTC's ownership of the cable underscores its commitment to enhancing connectivity within the Bahamas. As the country’s leading telecom provider, BTC has historically played a central role in developing and maintaining submarine cable systems to support the archipelago's unique needs. While no specific information is available regarding upgrades or the cable's current operational status, its initial deployment was a milestone in addressing the growing demand for reliable telecommunications services in the region.

What Our Measurements Show

Our live monitoring of the Grand Bahama Bimini Submarine Cable has provided valuable insights into its performance. The cable is divided into 12 measured corridors, enabling detailed analysis of its operational characteristics. The best recorded round-trip time (RTT) is 1 millisecond, indicating high-speed data transmission under optimal conditions. The average RTT across all corridors is 196 milliseconds, reflecting the typical latency experienced during regular operations.

These measurements highlight the cable's efficiency in supporting regional connectivity. The low RTT values are indicative of its ability to handle high-speed data transfer, which is crucial for internet services, enterprise applications, and telecommunications within the Bahamas. The cable's performance is particularly significant given the reliance of island nations on submarine systems for their digital infrastructure. By facilitating rapid and reliable communication, the Grand Bahama Bimini Submarine Cable contributes to the economic and social development of the communities it serves.
