Strategic Evolution Underwater Link (SEUL)

Overview

The Strategic Evolution Underwater Link (SEUL) is a submarine cable that spans 24 kilometers, connecting two key locations within Belize. It was officially ready for service in 2017 and is owned and operated by Belize Telemedia. This cable plays a crucial role in enhancing the telecommunications infrastructure of Belize, providing improved connectivity and supporting the country's growing demand for reliable internet services. While relatively short in length compared to international submarine cables, SEUL is strategically significant for its local context, as it directly links mainland Belize with one of its most important offshore communities.

SEUL is a domestic cable that helps bridge the digital divide within Belize by ensuring faster and more dependable communication between its landing points. Its introduction has contributed to the modernization of the country's telecommunications network, enabling better access to digital services for businesses, residents and tourists alike.

Route and Landings

The SEUL submarine cable connects two landing points in Belize: Bomba, located on the mainland, and San Pedro, situated on Ambergris Caye, the largest island of Belize. The route crosses a relatively shallow portion of the Caribbean Sea, making it technically less challenging to deploy compared to cables traversing deeper oceanic regions. This short yet vital link enhances connectivity between the mainland and one of Belize's most prominent tourist destinations.

Bomba is a small village in the Belize District, strategically chosen as a mainland landing point due to its proximity to key infrastructure and its location along the northern coastline. San Pedro, on the other hand, is a bustling town on Ambergris Caye, known for its tourism-driven economy and vibrant community. By connecting these two locations, SEUL supports the economic and social integration of the island with the mainland, ensuring that residents and businesses in San Pedro have access to the same level of digital services as those on the mainland.

Ownership and History

The Strategic Evolution Underwater Link is wholly owned and operated by Belize Telemedia, a leading telecommunications provider in Belize. Belize Telemedia is a government-owned entity, having been nationalized in 2009 to ensure better control over the country's critical communications infrastructure. SEUL represents a significant investment by Belize Telemedia in the development of domestic telecommunications capabilities.

The cable became operational in 2017, marking a milestone in Belize's efforts to enhance its digital infrastructure. By establishing a direct and reliable connection between Bomba and San Pedro, SEUL has helped improve internet access and reduce latency for users within the country. Its deployment reflects Belize Telemedia's commitment to supporting the nation's economic growth and digital transformation.

What Our Measurements Show

Our live monitoring of the SEUL cable provides valuable insights into its performance. Measurements are conducted across 80 distinct corridors, allowing for a comprehensive evaluation of the cable's operational efficiency. The best recorded round-trip time (RTT) is an impressive 1 millisecond, indicating minimal latency under optimal conditions. However, the average RTT across all measured corridors is 196 milliseconds, reflecting the variability in performance due to factors such as network load and routing.

The cable's low latency under ideal conditions is a testament to its importance in supporting high-speed communication within Belize. By providing a reliable link between Bomba and San Pedro, SEUL ensures that users on both ends experience improved connectivity, whether for personal communication, business operations or tourism-related activities. This performance highlights the cable's role in fostering a more connected and digitally inclusive Belize.
