Azores Fiber Optic System (AFOS)

Overview

The Azores Fiber Optic System (AFOS) is a submarine cable network located entirely within Portugal, designed to enhance connectivity among the islands of the Azores archipelago. With a total length of 1,100 kilometers, the system links seven key locations across the islands, providing a vital communications backbone for this remote Atlantic region. The cable became operational in 1998 and is owned and operated by Altice Portugal, a major telecommunications provider in the country. AFOS plays a critical role in supporting the telecommunications infrastructure of the Azores, ensuring reliable and high-capacity connections for residents, businesses, and public services.

By connecting multiple islands, AFOS addresses the unique challenges of maintaining robust telecommunications in an archipelago setting. Its deployment has significantly improved the quality and reliability of communications within the region, contributing to economic development and social cohesion. The system is a key component of Portugal's domestic telecommunications strategy, enhancing connectivity in one of the country's most geographically isolated areas.

Route and Landings

The Azores Fiber Optic System connects seven landing points across the Azores archipelago, ensuring comprehensive coverage of the region. The landing points include Angra do Heroismo, Faial, Graciosa, Ponta Delgada, São Mateus, Velas, and Vila do Porto. Each of these locations serves as a critical node in the network, linking the islands to one another and to the broader Portuguese telecommunications infrastructure.

Geographically, the cable traverses the deep waters of the North Atlantic Ocean, a challenging environment for submarine cable installation and maintenance. The Azores, located approximately 1,500 kilometers west of mainland Portugal, are composed of nine volcanic islands spread across three main groups. The AFOS cable connects islands from all three groups, including São Miguel and Santa Maria in the eastern group, Terceira, Graciosa, and São Jorge in the central group, and Faial in the western group. This strategic routing ensures that even the most remote communities in the Azores have access to reliable telecommunications services.

Ownership and History

The Azores Fiber Optic System is owned and operated by Altice Portugal, one of the country's leading telecommunications companies. The cable was commissioned to address the growing demand for reliable and high-speed communication services in the Azores, a region that had historically faced connectivity challenges due to its remote location in the Atlantic Ocean. The system became operational in 1998, marking a significant milestone in the region's telecommunications history.

Altice Portugal's investment in the AFOS reflects the company's commitment to improving infrastructure in all parts of the country, including its most remote regions. By linking the islands of the Azores, the cable has enabled the integration of the archipelago into Portugal's broader telecommunications network, facilitating economic growth, improving access to education and healthcare, and supporting local businesses. The AFOS has also contributed to Portugal's position as a key player in European and transatlantic telecommunications.

What Our Measurements Show

Our monitoring of the Azores Fiber Optic System indicates that the cable has maintained stable performance since its deployment. The system's design and construction have proven resilient in the face of the challenging environmental conditions of the North Atlantic, including deep-sea pressures and potential seismic activity associated with the region's volcanic origins. The cable's operational reliability has been a cornerstone of its success in supporting the Azores' connectivity needs.

Probes into the system's performance reveal that it has been instrumental in providing consistent bandwidth to the islands it serves. This has allowed for the seamless operation of critical services such as government communications, emergency response systems, and internet access for residents and businesses. The AFOS has also supported the region's growing tourism industry by enabling modern digital services, which are increasingly essential for both visitors and local enterprises. Overall, the cable has been a vital asset in bridging the digital divide for the Azores, ensuring that the region remains connected to the rest of Portugal and the world.
