The world is witnessing a digital transformation driven by high-speed internet, reshaping economies and revolutionising industries on a global scale. Countries with robust internet infrastructure are experiencing unprecedented growth in commerce, education, healthcare, and innovation. Africa, with its young population and rapidly growing digital ecosystem, stands on the brink of a technological revolution that could unlock immense economic potential.

Fibre internet, at the heart of this revolution, delivers ultra-fast, reliable, and energy-efficient connectivity by transmitting data through thin strands of glass or plastic via light signals. Unlike traditional broadband or satellite connections, fibre internet offers unmatched speed and stability, making it the gold standard for modern internet access. Its ability to support high-bandwidth activities and power emerging technologies positions fibre as a key enabler of Africa’s digital and economic growth in the coming decades.

Economic Impact of Fibre Infrastructure Across Africa

The economic implications of improved fibre connectivity in Africa are substantial and measurable. Studies conducted by RTI in partnership with Facebook reveal that subsea cables-the backbone of internet connectivity-have dramatically transformed economic outcomes across the continent. Areas connected to fibre have experienced over 8 percent increases in employment, while countries like the Democratic Republic of Congo have seen GDP per capita rise by an impressive 19 percent following fibre implementation.

The impact of major projects like 2Africa, a 37,000-kilometer subsea cable system, demonstrates the transformative power of fibre infrastructure. This single project is estimated to generate between $26.2 and $36.4 billion in economic impact for Africa’s GDP within just 2-3 years of becoming operational, representing approximately 0.42 to 0.58 percent of the continent’s GDP at purchasing power parity. Such figures underscore how strategic investments in digital infrastructure yield disproportionately positive economic returns.

Productivity and Business Resilience

Fibre connectivity has proven particularly valuable in countries facing infrastructure challenges. In South Africa, where power interruptions have historically hampered business operations, fibre technology has emerged as a beacon of resilience. Unlike traditional copper cables, fibre optics are less dependent on the electrical grid, making them less vulnerable to power outages. This resilience has allowed businesses to leverage fibre connectivity to maintain operational continuity during loadshedding, protecting revenue streams and contributing to broader economic stability.

Research from the International Finance Corporation demonstrates a strong positive correlation between increased digitalisation and higher levels of firm productivity. Businesses intensively using digital technologies enabled by fibre connectivity can enhance operational efficiency, access new markets, and integrate into global value chains. This technological advantage creates competitive businesses better positioned to contribute to national economic growth.

Major Fibre Projects Transforming Africa’s Digital Landscape

Submarine Cable Expansion

Africa’s digital transformation is accelerating through ambitious submarine cable projects. Current projections indicate that planned expansions of submarine fibre-optic cables will increase international internet bandwidth sixfold by 2027. This dramatic increase in connectivity is expected to lower broadband prices while stimulating up to $32 billion in related investments over the next five years, creating a virtuous cycle of digital growth and economic development.

The continent has witnessed substantial growth in terrestrial fibre deployment as well. However, the UN Broadband Commission estimates that Africa still requires an additional 250,000 kilometres of fibre and 250,000 cellular base stations to achieve ubiquitous 4G coverage by 2030. Telecommunications operators are responding to this need, planning to invest approximately $45 billion between 2019 and 2025 specifically to address last-mile connectivity challenges.

National Fibre Initiatives

Individual countries are launching ambitious fibre projects to accelerate economic growth. Nigeria, Africa’s largest economy, recently partnered with West Indian Ocean Cable Company (WIOCC) on a $10 million fibre-to-home internet connectivity project. The initiative’s first phase targets three million homes with plans for nationwide expansion. This project aligns with Nigeria’s broader economic objectives, with government officials emphasising digital technology as a driver of productivity and a cornerstone of their vision to build a $1 trillion economy.

The project addresses a critical gap in Nigeria’s digital infrastructure. Currently, most Nigerians rely on mobile internet, which lacks the speed and reliability necessary for many modern digital applications. By transitioning to fibre-to-home connectivity, the initiative aims to create a more connected environment supporting individuals, businesses, and institutions throughout the country.

Strategic Initiatives for Digital Transformation

Smart Africa Alliance’s Vision

The Smart Africa Alliance has developed an ambitious initiative called SMART Broadband 2025 to dramatically increase digital connectivity across the continent. The strategy aims to increase broadband penetration by 50% from 34% in 2019 to 51% by 2025, connecting an additional 308 million people to broadband services. This initiative recognises that broadband connectivity is foundational to achieving a Single Digital Market in Africa by 2030.

The strategy acknowledges the uneven development of broadband infrastructure across Africa, with some countries achieving high penetration rates while others struggle with limited access to undersea fibre connections. The Alliance has determined that a minimum 20% penetration rate is necessary for countries to experience the network effects needed to support a digital economy. To achieve this threshold across the continent, coordinated cross-border initiatives are essential.

Digital Start-up Ecosystem Growth

Africa’s digital start-up ecosystem is flourishing alongside improvements in fibre infrastructure. Between 2016 and 2021, the number of tech hubs across the continent tripled, creating innovation centres that leverage high-speed connectivity to develop solutions for local challenges. These start-ups are increasingly incorporating disruptive technologies in sectors like agriculture, health, and education, helping to overcome financial barriers while promoting widespread digital integration.

Challenges and Regional Disparities

Despite the positive trajectory, significant challenges remain in achieving equitable fibre connectivity across Africa. As of 2020, approximately 45% of Sub-Saharan Africa’s population lived beyond 25 kilometres from a fibre node, indicating substantial gaps in infrastructure coverage. Additionally, at least three countries still lack fibre connectivity to undersea cables, while others don’t have the multiple cross-border fibre access points necessary for network redundancy.

Broadband penetration rates vary dramatically across the continent, with some countries reporting rates below 10% and others exceeding the regional average of 34%. These disparities highlight the need for targeted investments in underserved regions to ensure that the economic benefits of fibre connectivity are distributed equitably.

Addressing the Digital Divide

Experts identify several key strategies to address these challenges:

Enhancing middle and last-mile digital infrastructure to improve access while reducing connectivity costs.
Promoting competition among service providers to drive down prices and improve service quality.
Supporting innovative tech start-ups that offer affordable digital solutions to facilitate technology adoption among firms.

Economic Outlook for Fibre-Enabled Growth

The economic potential of widespread fibre adoption in Africa is substantial. South Africa provides a concrete example of fibre’s economic impact, where the technology has created jobs, spurred local industry development, and attracted foreign investment. These benefits extend beyond urban centres, with fibre infrastructure increasingly serving as a foundation for rural digital inclusion initiatives.

For countries like Nigeria with ambitious economic growth targets, fibre infrastructure represents a critical enabler. By improving nationwide internet infrastructure, fibre initiatives aim to foster more inclusive digital economies, ensuring that citizens and businesses throughout the country benefit from high-speed connectivity opportunities.
