Largest optical cable

The 2Africa cable, spanning approximately 45,000 kilometers, is currently the world's largest optical fiber cable.Overview of the 2Africa CableThe 2Africa cable is a monumental submarine fiber optic project designed to enhance internet connectivity across Africa, the Middle East, and Europe. Announced in May 2020, it is spearheaded by a consortium including Meta (formerly Facebook), China Mobile International, MTN GlobalConnect, Orange, stc, Telecom Egypt, Vodafone, and WIOCC . The cable is engineered to encircle the African continent, connecting 23 countries and providing a transformative boost in internet infrastructure.Specifications and TechnologyLength: Approximately 45,000 kilometers, making it one of the longest subsea cable systems in the world .Capacity: Designed to deliver up to 180 terabits per second on key segments, surpassing the combined capacity of all existing subsea cables serving Africa .Technology: Employs Spatial Division Multiplexing (SDM1), which allows more fiber pairs per cable and higher data throughput, meeting the growing demand for bandwidth .Impact on ConnectivityThe 2Africa cable is expected to dramatically improve internet access in regions with historically limited infrastructure. For Africa, this means:Faster and more reliable internet for millions of peopleEnhanced access to education, healthcare, and communication platformsImproved opportunities for businesses to connect to global markets and leverage digital tools for growth Comparison with Other Major CablesPreviously, the Fibre-optic Link Around the Globe (FLAG) was one of the longest cables, spanning 28,000 kilometers and connecting the UK, Japan, India, and other regions . While FLAG was a pioneering system in the 1990s, the 2Africa cable surpasses it in both length and capacity, reflecting advances in fiber optic technology and global connectivity needs .ConclusionThe 2Africa cable represents the current pinnacle of submarine fiber optic infrastructure, combining unprecedented length, massive data capacity, and cutting-edge technology. Its deployment is set to bridge the digital divide, particularly in Africa, and reshape global internet connectivity for years to come .
