What is business fibre?
What is business fibre? It is an internet connection delivered over a fibre-optic line to a business premises, sold with commitments that a home service does not carry: how quickly faults are repaired, how much the capacity is shared, which IP addresses you get and who answers when something goes wrong. Fibre to the business (FTTB) and fibre to the home (FTTH) often run through the same streets, and the differences lie less in the glass than in how the service is built, sold and supported.
Much of South Africa's fibre is open access: a fibre network operator builds and owns the fibre in the street, and internet service providers sell services over it, so the same network can carry home and business products from several providers. That is why two offices on one street can have very different experiences of the same fibre.
Business services come in two broad families:
- Business broadband fibre. Shared capacity, like home fibre, but usually with lower contention, a written service-level agreement, faster fault handling, static IP addresses and business support hours.
- Dedicated business fibre. Capacity reserved for you, often called dedicated internet access or an uncontended line: symmetrical speeds, the tightest service-level agreement and a higher price. It suits head offices, data rooms and any site where the connection is critical.
This guide is part of our insights on IT and connectivity.
Uncapped, unshaped and unthrottled fibre: what the terms mean
Fibre adverts lean on three words, and each has a precise meaning:
Uncapped. There is no monthly data limit, so you are not cut off or charged extra for using more.- Unshaped. The provider does not slow particular kinds of traffic, such as video streaming, large downloads or file sharing, to favour others.
- Unthrottled. The provider does not reduce your speed after you pass a usage threshold during the month.
Uncapped unshaped unthrottled fibre is a common promise in fibre adverts, but read the fair use policy behind it: that document can still limit how an "uncapped" service behaves. Two more terms matter as much. The contention ratio says how many users share the capacity, and a lower ratio means more consistent speeds. The advertised speed is the line rate, the most the line can carry, not a commitment; business agreements are where a provider commits to what you will actually get.
For a household, uncapped unshaped fibre on a good network is usually enough. For an organisation, uncapped unthrottled fibre answers only part of the question, because a line with no data limit and no service-level agreement can still leave you offline for longer than the business can afford.
Business vs home internet: when a home package is enough, and when it is not
A home package can be enough for:
- one or two people working from home in cloud applications;
- work that can pause for a few hours, with a mobile hotspot as a stopgap;
- a site where nobody outside the building needs to reach anything on the network.
Choose business internet when:
- a team, a reception desk or a contact centre depends on the line all day;
- you run VoIP, video meetings throughout the day, or cloud backups that upload large volumes; see VoIP for business;
- anything must be reachable from outside, such as a VPN, a server, a camera system or a portal, which needs a static IP address;
- the site is a branch linked to head office or to other sites;
- an outage has a cost you can name: lost sales, missed appointments, learners offline or a municipal counter closed;
- a contract, an auditor or an insurer expects documented service levels.
If you are weighing a home product for business use, check that its terms allow business use and the services you need, such as hosting or a VPN.
How to choose a business fibre provider
- Coverage. Which networks reach your building, and whether new fibre must be built.
- The service-level agreement in writing. Restoration targets, service credits, how faults are logged and escalated, and support hours.
- Contention and symmetry, stated in the contract rather than implied in an advert.
- The fair use policy behind any "uncapped" promise.
- Static IP addresses, and who holds the router and firewall credentials.
- A backup option on a different network or technology, with failover.
- Contract term, notice period and cancellation costs.
- One bill and one number for support, rather than a network operator, an ISP and an IT company pointing at each other.
- Industry standing, such as membership of the Internet Service Providers' Association of South Africa (ISPA) and its Code of Conduct.

Governance, compliance and procurement
- Governance. Connectivity faults are logged and tracked like any other incident, prioritised from P1, a critical outage, to P4, a low-impact request, with targets agreed in your SLA, and reported in the monthly service review.
- Compliance. Firewalled, monitored connections support POPIA's requirement (section 19) for reasonable technical measures to protect personal information, and public bodies get documentation that suits PFMA and MFMA audits.
- Procurement. Arke Technologies (Pty) Ltd is a Level 1 B-BBEE contributor (sworn affidavit available on request), giving buyers 135% procurement recognition. Company documents, our CSD supplier number and SARS tax compliance status are available on request. You can buy on a written proposal and SLA against your purchase order, or through a tender, for which we complete the standard bidding documents (SBD forms).
- Continuity. Router and firewall credentials, IP address records and network documentation are yours.
