Structured cabling and network cable installation, certified and documented
Network cable installation, done properly, is structured cabling: a standards-based system of Cat 6, Cat 6A and fibre running from every network point to patch panels in a managed rack. Arke Technologies designs, installs, certifies and documents it for organisations, public buildings and schools across South Africa, from Johannesburg.
What is structured cabling in networking?
Structured cabling is a standardised way to wire a building's LAN (local area network) for data. Instead of running a separate cable from a switch to each computer, installers lay permanent cables from wall outlets to patch panels in a central rack, then connect equipment with short patch leads. Every link is built to the same rules, tested and labelled, so the whole structured cabling system behaves predictably.
The terms overlap. Network cabling, data cabling, IT structured cabling and infrastructure cabling all describe the same layer: the physical network infrastructure cabling that every switch, access point, phone and camera depends on. Cabling and wiring differ mainly in what they carry: wiring usually means electrical power, while cabling carries data and voice. The two must be kept apart in every ceiling and riser.
A network with very little cabling is usually a wireless one, but it still depends on cables: every Wi-Fi access point connects to a switch by cable, and most draw their power over it. Good business Wi-Fi starts with the structured cabling network beneath it. We plan, install and support that layer as part of our network infrastructure services, beneath the firewalls and SD-WAN that run over it.
Structured cabling components
The international standards (ISO/IEC 11801 and the ANSI/TIA-568 series) divide a building's cabling into subsystems. The components of structured cabling we specify and install:
- Work-area outlets. The network points at desks, in classrooms and in ceilings, fitted with RJ45 connectors for copper or LC connectors for fibre.
- Horizontal cabling. The permanent run from each outlet to the comms cabinet on that floor: up to 90 metres of fixed cable, within a 100-metre channel including patch leads.
- Patch panels and cable management. Each run terminates on a server rack patch panel, with horizontal and vertical managers so every patch lead stays traceable.
- Racks and cabinets. Floor-standing or wall-mounted, sized for today's equipment plus growth, with power distribution, earthing and airflow planned in.
- Backbone cabling. Fibre, or copper for short links, between cabinets, floors and buildings.
- Containment. Trunking, cable trays and conduit that protect the cable and keep it separated from electrical power.
- Labels and records. A label at both ends of every cable, matched to the drawings and the test results.
Structured cabling benefits, and the cost of bad network cabling
The benefits of structured cabling show every time something changes. Moving a desk means moving a patch lead, and a fault is traced quickly because every link is labelled. New access points, cameras and door controllers plug into spare points instead of triggering new work. And a certified installation outlasts several generations of the switches and access points connected to it.
Bad network cabling shows up as symptoms that are often blamed on something else: links that drop at random, computers that connect at 100 Mbps instead of 1 Gbps, access points that reboot under load, and a cabinet nobody dares to touch. The usual causes are untested terminations, CCA cable, runs beyond the length limit, cables laid across power, and no records. We also test and document existing installations, so you know what you have before replacing it.
Network cabling standards and requirements
We design and test to recognised network cabling standards, so anyone can verify the result:
- ISO/IEC 11801 and ANSI/TIA-568 for cabling performance, channel lengths and testing.
- ANSI/TIA-569 for pathways and spaces, including separation from electrical power.
- ANSI/TIA-606 for labelling and administration records.
- ANSI/TIA-607 for bonding and earthing of racks and cable screens.
- Your building's rules: fire-rated penetrations, low-smoke zero-halogen sheathing where the specification requires it, and facilities approval for ceilings and risers.
Where we install: corporate, public-sector and school buildings
Government and municipal buildings
Records that suit PFMA and MFMA asset management: every rack, panel and point listed, tested and handed over for the asset register.
Schools, colleges and campuses
Classrooms, labs and admin blocks, with points for access points and interactive displays, and fibre between buildings. See school networks and Wi-Fi.
Warehouses, clinics and branches
Long runs and harsh environments, where fibre and shielded cable earn their cost.
We serve organisations across South Africa, and take on work beyond it. If you are looking for home network cabling, most homes are better served by fibre and mesh Wi-Fi, which Fibre Boyz (opens fibreboyz.co.za), our connectivity division, connects and supports.
Network cabling installation cost: what drives the price
Last reviewed: September 2026
Network cable installation cost depends on the building more than the cable, so we quote a fixed price after a site survey. Commercial network cable installation pricing is usually expressed per point, plus racks, backbone and containment, and our quotes are itemised the same way. What moves the number:
- Number of network points and how they cluster.
- Cable category: Cat 6A and fibre cost more to buy and to install than Cat 6.
- Routes and access: open ceilings are quick; concrete, heights, occupied spaces and heritage buildings are slow.
- Containment: new trunking or trays versus existing routes.
- Racks, patch panels and power, including a UPS for the cabinet during load-shedding.
- Testing, certification and documentation: part of every quote, never an optional extra.
- After-hours work, when a live office or school cannot be disturbed.
The cheapest network cabling installation often carries the highest net cost: untested links, CCA cable and missing records are paid for later in downtime and rework. For cabinet, switch and UPS prices, see Server Hub (opens serverhub.co.za), our hardware division, and our IT hardware page.
Governance, compliance and procurement
Cabling is a long-lived asset, so we deliver records a board, an auditor or the next contractor can rely on.
- Governance. A named project lead, a fixed scope and change control: any extra point is a written variation, priced before work starts, and snags are closed before handover.
- Compliance. Comms cabinets are lockable and access-controlled, because POPIA expects reasonable physical as well as technical measures to protect personal information. Test reports and as-built records support ISO 27001-aligned asset control.
- Procurement. Arke Technologies is a Level 1 B-BBEE contributor (sworn affidavit available on request), which gives buyers 135% procurement recognition. Company documents, our CSD supplier number and tax compliance status are available on request, and we complete standard bidding documents when a tender requires them. See procurement and compliance.
- Continuity. The drawings, cable schedule, test results and labelling scheme are yours, so any competent team can extend the installation later. If we manage your IT, the same records feed network monitoring and support.
How to choose network cabling companies in South Africa
Most network cabling companies can pull cable; fewer can prove the result. When you compare structured cabling companies, data cabling companies or network cabling contractors, ask each installer for:
- A site survey before the quote, not a price per point over the phone.
- A design, a network cabling diagram and certification test results for every link, all of which you keep.
- Solid-copper cable from a named manufacturer, never CCA.
- One contract and one accountable team for design, installation and support, so your cabling solutions and the network services running on them are not split across suppliers.
