The Sirius South submarine cable is a high-capacity fiber-optic cable that spans approximately 6,400 kilometers across the South Atlantic Ocean, connecting Brazil and South Africa. The cable system is a joint venture between a consortium of telecommunications companies, including Angola Cables, Broadband Infraco, Google, and Ocean Network Express.
The Sirius South submarine cable has a design capacity of 72 terabits per second and serves to provide high-speed internet connectivity between South America and Africa. The cable is designed to withstand harsh weather conditions and has been equipped with advanced technology to ensure reliable and secure data transmission.
The project was initially announced in 2017 and was completed in early 2021. The construction of the cable system involved significant engineering and logistical challenges, including the laying of the cable in deep waters and the implementation of advanced cable protection measures.
The Sirius South submarine cable is expected to have a significant impact on the connectivity and economic development of both South America and Africa, enabling faster and more secure data transfer between the two regions. It also serves as a critical backup for other existing cable systems in the region, ensuring continued connectivity even in the event of cable damage or system failures.
