Open-access fibre networks have emerged as a transformative force in South Africa’s telecommunications landscape, fundamentally reshaping how broadband infrastructure is deployed and accessed across the country. These networks operate on a model where multiple Internet Service Providers (ISPs) can utilise the same physical infrastructure, creating competition at the service level while maximising the efficiency of capital investment in network deployment.
This approach has proven particularly effective in South Africa, where the combination of geographic challenges, economic constraints, and historical telecommunications monopolies created significant barriers to widespread broadband adoption.
Understanding the Open-Access Model
Key Benefits
Open-access networks deliver several critical advantages in the South African context:
Economic Efficiency: By sharing infrastructure costs across multiple service providers, open-access networks reduce the overall investment burden and make fibre deployment economically viable in areas that might otherwise be unprofitable.
Consumer Choice: Customers can select from multiple ISPs operating on the same network, leading to competitive pricing and improved service offerings.
Accelerated Deployment: The model has facilitated rapid fibre rollout across South Africa, with countries like Sweden and South Africa being cited as success stories for this approach.
Market Competition: Open access lowers barriers to entry for ISPs, promoting healthy competition and innovation in service delivery.
Current State of South Africa’s Fibre Market
Market Size and Growth
South Africa’s fibre market has experienced explosive growth over the past decade. Fixed broadband subscriptions surged from 1.4 million in 2023 to an impressive 2.7 million by the end of 2024, with fibre-to-the-home and fibre-to-the-building subscriptions increasing from 1.0 million to 2.4 million. This growth contributed a substantial R6.5 billion in revenue to the telecommunications sector.
The fibre subscriptions across homes and businesses have risen by over 4,200% over the last seven years, demonstrating the rapid adoption of fibre technology. Fibre-to-the-Home (FTTH) penetration has surpassed 20% in urban areas, with annual subscription growth rates exceeding 30% in recent years.
Major Network Operators
South Africa’s fibre landscape is dominated by several key players operating on open-access principles:
Vumatel leads the market with the largest fibre-to-the-home network, serving over 2 million homes passed and maintaining 830,000 FTTH customers with a 32% market share. Despite its size, Vumatel received the lowest ratings among major networks in ISP perception surveys, scoring 4.7 out of 10.
Openserve (Telkom’s wholesale division) operates South Africa’s second-largest network with over 1.3 million homes passed and 667,465 connected homes, achieving a superior connectivity ratio of 49.79%. Openserve scored highest for reliability and value for money among major operators.
Other Major Players include MetroFibre (510,000 homes passed), Frogfoot (406,000 homes passed), Octotel (372,000 homes passed), and emerging networks like Herotel with strong connectivity ratios of 50.01%.
Coverage and Accessibility
Currently, 5.4 million unique South African homes have access to fibre connectivity, representing 28% of households based on Statistics South Africa’s household survey data. Coverage varies dramatically by income level: 95% of upper-middle income households (approximately 700,000 homes) have fibre access, while only 50% of lower-middle segment households (3 million homes) are served.
Geographically, the Western Cape and Gauteng lead in both fibre coverage and consumer choice, while provinces like Limpopo and Northern Cape remain significantly underserved. This disparity highlights the ongoing challenge of bridging the digital divide between urban and rural areas.
Government Policy and Regulatory Framework
National Broadband Policy
The South African government established a comprehensive broadband policy framework in 2013, launching the SA Connect initiative with the ambitious goal of achieving universal broadband access by 2030. This policy creates an enabling environment for broadband infrastructure rollout through both public and private sector collaboration.
Recent policy updates have accelerated these timelines significantly. The government now targets 80% broadband connectivity by 2024, a dramatic acceleration from the original 2030 goal. The Department of Communications and Digital Technologies allocated R1.6 billion for the 2024/25 financial year to support Phase 2 of the SA Connect project.
SA Connect Implementation
The SA Connect project has achieved notable progress, connecting over 751,232 households through approximately 4,366 Wi-Fi hotspots across 11 district municipalities as of April 2024. The initiative involves 76 Internet Service Providers, many of which are small, medium, and micro enterprises (SMMEs), creating an estimated 4,500 direct jobs.
The government’s long-term strategy includes connecting 5.5 million households through Wi-Fi hotspots over the next three to four years, with interim targets of 1.5 million households by December 2024.
Regulatory Environment
South Africa’s regulatory framework, governed primarily by the Electronic Communications Act of 2005, promotes competition and open access principles. The Independent Communications Authority of South Africa (ICASA) serves as the primary regulator, working to ensure fair competition and access to telecommunications infrastructure.
The regulatory environment has evolved to support open-access models, with policies encouraging infrastructure sharing and wholesale access to dominant operators’ networks. This regulatory support has been crucial in enabling the rapid growth of open-access fibre networks across the country.
Economic Impact and Investment
Economic Benefits
Fibre infrastructure deployment has generated substantial economic benefits for South Africa. Research indicates that submarine fibre optic cable arrivals led to a 6.1% increase in GDP per capita between 2009 and 2014. Each 10% increase in broadband penetration correlates with a 0.27% increase in GDP per capita.
Employment impacts are concentrated in areas with fibre connectivity, with subsea cable arrivals increasing employment likelihood by 2.2% in fibre-connected areas. The financial sector has particularly benefited, showing robust increases in net firm creation in fibre-connected regions.
Investment Trends
Major investments continue to flow into South Africa’s fibre infrastructure. Recent examples include a R160 million investment in expanding the Yangtze Optics Africa Cable optical fibre manufacturing facility in KwaZulu-Natal, creating Africa’s largest optical fibre cable manufacturing plant.
MetroFibre secured significant funding for a R3 billion expansion program to connect an additional 300,000 homes across South Africa. Dark Fibre Africa has invested over R10 billion and installed close to 14,000 kilometres of fibre infrastructure nationwide by 2018.
Revenue Generation
The telecommunications sector generated substantial revenue through fibre-enabled services, with R159.3 billion generated from social media platform access alone in 2024. Major platforms, including Facebook (R58.9 billion), WhatsApp (R49.2 billion), and TikTok (R38.9 billion), contributed significantly to this revenue stream.
