Structured Cabling, Certified Run By Run
A structured cabling run gets tested to the TIA/ISO standard, certified and sealed behind the wall, where it stays long after the invoice is paid. We install and certify structured cabling as part of the wider IT infrastructure services we provide, so every run is proven before the ceiling closes and the network built on it never inherits a fault nobody can find.
Five Cabling Assumptions That Cost More To Fix Later
Most cabling quotes read the same regardless of the building, and that is usually the first sign nobody has actually planned the run for this site. A structured cabling job is either engineered per building or guessed, and the difference only shows up months after handover, once someone tries to add a device that the network was never sized for.
Any Cable Category Will Do The Job
It will not. We choose cable category per run against required bandwidth and distance, not one spec applied across the whole site: a comms room backbone often runs fibre while desk drops run copper.
Running Cable Is The Whole Job
Pulling cable without planning containment first is how runs end up draped over lighting ballasts and power cabling, the two things most likely to introduce interference on a line nobody has tested yet.
The Comms Room Is An Afterthought
A rack of unlabelled patch cords with no airflow plan is the most common cause of intermittent faults we get called back for. Patch panels, switches, power and cooling get designed together, not bolted on later.
A Visual Check Is The Same As Certification
Seeing a green light on a terminated point is not certification. Every run we hand over is tested for length, wire map, crosstalk and insertion loss, and produces a pass or fail result on paper.
Labelling And Records Can Wait Until Later
Unlabelled points and no records mean every future move, add or fault starts with tracing cable through a ceiling. We label both ends of every run and map it to a patch panel port while the installers are still on site.our team already uses, on a live call, before anyone leaves site.
On their own, these are irritations. Together they mean intermittent faults nobody can trace, a comms room that turns every new install into a troubleshooting job, and a network that was never sized for the devices now plugged into it. As your structured cabling partner in Johannesburg, we design, certify and document the cabling as one system, not a pile of runs pulled to spec sheet minimums, so it still works when the office changes around it.
Everything That's In Scope From The First Site Walk To Handover
A cabling quote should tell you exactly what happens between the first site walk and the day the team leaves. This is what sits inside every project we scope for, in the order it actually happens, so you can check any quote against it before signing, rather than finding out what was skipped once the invoice lands.
Point Count And Site Walk
Every desk, access point, camera and printer gets counted and mapped to a data point before a single cable is ordered, so the design matches the floor plan, not a rough estimate.
Pathway And Containment Design
Trunking, ducting and ceiling void routes get planned in advance so every run stays within standard length limits and clear of power and lighting interference.
Cable Category Selection Per Run
Category is chosen against the bandwidth and distance each run actually needs, so a backbone link and a desk drop rarely share the same spec.
Comms Room And Rack Build
Patch panels, switches, cable management, power and cooling get built or tidied as one job, feeding the physical layer our installs run on.
Termination And Labelling
Every run is terminated cleanly to spec and labelled at both ends, so a point can be traced to a patch panel port without opening a ceiling.
Certification Of Every Run
Each cable is tested on completion and the result recorded, so every run gets a verdict on paper, not a check across a handful of points.
Ninety Metres And One Hundred Percent Tested, Every Run
The TIA/ISO structured cabling standard sets a hard ceiling on every copper run we install: a permanent link no longer than 90 metres, and a full channel, link plus patch cords, no longer than 100 metres. We treat that as a fixed engineering limit, not a guideline to work around on a tight floor plate.
The 90 Metre Ceiling
Every permanent link is measured and planned against this limit before anything is terminated, not checked afterwards when it’s too late to reroute.
Certified, Not Assumed
Each run is tested on a handheld certifier for length, wire map, crosstalk and insertion loss, producing a pass or fail result you keep on file.
The Same Standard In The Rack
Backbone runs, patch panels and rack layout are held to the same standard as the desk points, and the room is only closed up once every result is on file.
The Fibre Backbones Tested Too
Fibre backbone links are tested for loss and polarity before handover, so the link between floors or rooms carries the same pass or fail record as the copper.
What Actually Drives Structured Cabling Pricing
Two projects with identical headcounts can land on very different invoices once you factor in cable category, the condition of the existing comms room, and the complexity of the pathways. An office with clean runs to every desk and a tidy rack costs far less than a building with undocumented legacy cabling, a comms room that needs a full rebuild, and risers across several floors. That’s why every quote we give starts with a site walk rather than a number over the phone.

Who This Is For
This fits office relocations, space fit outs and network cabling installation for Johannesburg SMEs, including sites where the existing cabling was never documented. We have walked into enough comms rooms with unlabelled patch panels and daisy-chained switches to know a proper audit always comes first. It does not fit a one-off faulty link, a standalone meeting room fit out (that's boardrooms), multi-site network design (that's secure SD-WAN), or general Wi-Fi coverage on an already-cabled network (that's enterprise wireless).
How it works
frequently asked questions
Can you work with the cabling we already have?
Yes, where it tests clean. We audit the existing runs, certify what passes and flag what needs replacing, so you only pay to re-cable what has actually failed.
What warranty applies if a cable run fails years from now?
Every run is certified on completion, and you keep the test results as the baseline for any future fault. Our workmanship guarantee covers the install itself. Where the cabling system carries a manufacturer warranty on the cable and connecting hardware, we state the terms in your quote before you sign.
How many data points do we actually need for our office?
That number comes out of the site walk, not a price list. Every device on your floor plan is mapped to a data point before a single cable is priced, so the quote matches how your office in Johannesburg actually runs, not a generic template. Where coverage is thin, the walk often flags a case for additional enterprise wireless access points alongside the wired points.
Do you handle the comms room and rack, or only the desk points?
Both. The rack, patch panels, switches, cable management, power and cooling are part of the same project, not quoted as a separate job later. A comms room left as an afterthought is usually where the first fault shows up.
How long does a typical office cabling install take?
A full office of structured cabling depends on the point count, the floor plan and how much of the pathway already exists. We confirm the timeline during the site walk and put it in the quote, rather than guess over the phone.
