Key Questions Answered
What is the significance of the 2Africa subsea cable system?
The 2Africa subsea cable system is significant as it is the world's longest open access subsea cable, connecting 33 countries and enabling connectivity for 3 billion people. This infrastructure is designed to enhance digital experiences, accelerate economic growth, and support high-speed internet access across Africa, Europe, and Asia.
How does the 2Africa cable improve internet capacity in Africa?
The 2Africa cable supports a total trunk capacity of up to 180 terabits per second (Tbps), which is enough to stream over 36 million HD movies simultaneously. This massive capacity allows internet service providers to secure bandwidth at lower wholesale prices, fostering competition and improving access to digital services.
What innovative technologies were used in the construction of 2Africa?
The construction of the 2Africa cable utilized advanced spatial division multiplexing (SDM) technology, allowing for up to 16 fiber pairs per cable. This innovation doubles the capacity of older systems and includes features like undersea optical wavelength switching for flexible bandwidth management.
What partnerships were involved in the 2Africa project?
The 2Africa project involved a consortium of global partners led by Meta, including Bayobab, center3, CMI, Orange, Telecom Egypt, Vodafone Group, and WIOCC. These partnerships were crucial for designing and investing in the infrastructure to enhance connectivity across multiple regions.
