Dark Fibre Africa (DFA) — wholesale open-access fibre network
Dark Fibre Africa builds and leases the fibre other providers sell over. Its open-access network runs to more than 20,000 km and reaches roughly 85% of metropolitan areas in South Africa’s major cities, leased to mobile operators, fibre network operators, ISPs and the public sector. DFA is wholesale — it does not sell internet to businesses or homes.
Key facts
| Who they are | Dark Fibre Africa (Pty) Ltd, describing itself as South Africa’s premier wholesale, open-access connectivity provider, and part of a wider group. |
| What they actually sell | Infrastructure on lease, not internet service. The secure transmission and backbone fibre is available to the public sector, mobile operators, fibre network operators and ISPs — the companies who then sell to you. |
| Network | Over 20,000 km of dark fibre covering approximately 85% of metropolitan areas in all key South African cities. DFA finances, builds, installs, manages and maintains the network end to end. |
| Products | Dark Fibre, Titan and Peregrine Long Haul, plus managed services Calypte Metro and Calypte Long Haul. |
| Becoming a provider on it | The route onto the network is licensed: an ECNS licence is required to apply as a connectivity provider. Property developers, OEMs and system integrators partner separately. |
| For homes | DFA routes residential enquiries to Vumatel rather than serving them directly. |
| Recent | In 2025, DFA with Ciena and deployment partner Willcom reported a record fibre capacity trial delivering more than four times previous performance. Paul Divall was appointed Chief Commercial Officer in December 2025. |

Open access, and why it decided your fibre bill
Open access is the reason South African fibre pricing fell. Under the older model the company that laid the fibre also sold the service, so whoever trenched your street owned you. An open-access operator separates the two: DFA builds and maintains the physical network, then leases capacity to any licensed provider, and those providers compete for your business over the same strand. That is why several ISPs can quote you on one line. It also means DFA has no retail product and never will — the commercial relationship is with operators, and the licence requirement to get onto the network is a regulatory gate, not a sales process. If you want a business line, compare the verified providers, several of whom may deliver it over exactly this infrastructure.
Who Dark Fibre Africa is a fit for
- Licensed operators and ISPs needing metro or long-haul capacity on an open-access network
- Mobile operators requiring backhaul across South African metros
- Property developers, OEMs and system integrators partnering on network deployment

Can my business buy internet from DFA?
No. DFA is a wholesale, open-access infrastructure operator. It leases fibre to mobile operators, ISPs and fibre network operators, who sell the services you buy.
What is open access?
The network owner and the service provider are separate companies. DFA builds and maintains the fibre, then leases capacity to any licensed provider, so several ISPs can compete to serve you over the same line.
How big is the DFA network?
More than 20,000 km of dark fibre, covering roughly 85% of metropolitan areas in South Africa’s key cities.
How does a provider get onto the DFA network?
It must hold an ECNS licence and apply. It is a regulatory qualification rather than a commercial sign-up.
I want fibre at home — what now?
DFA itself routes residential enquiries to Vumatel. For a business line, compare the verified providers in the WhichVoIP fibre comparison.
Is my existing fibre already on DFA?
Possibly, without you knowing. Ask your ISP which network operator carries your line — it determines coverage, install times and who fixes a physical fault.
