Structured Cabling Services in Rwanda

What is structured cabling, and who needs it

Structured cabling replaces cables run wherever was convenient with a system built to a standard: horizontal runs from each outlet to a patch panel, a backbone between comms rooms, consistent termination, containment, labelling and test results for every run. It’s the physical layer under the network installation, Wi-Fi, CCTV and phones. New offices, schools, clinics and hotels need it from the start; existing sites need it when the old cabling has become a source of faults.

The problem it solves

Untracked cabling turns every fault into an investigation. Which cable is this? Where does it go? Why does unplugging it disconnect a different desk? Structured cabling replaces that with a system where a port number tells you exactly what it serves, and a suspect run can be re-tested and proven faulty instead of argued about. It also removes the hidden performance problems that come from damaged, over-length or badly terminated cables, which look like slow computers or flaky Wi-Fi.

Choosing the cable category

The decision that lasts longest is the cable category, because replacing cable means opening ceilings and walls again.

• Cat6 carries Gigabit Ethernet over the full 100-metre channel, and 10-Gigabit only over roughly 37 to 55 metres, depending on interference between neighbouring cables. It suits most desk outlets.
• Cat6A carries 10-Gigabit over the full 100 metres. It costs more and is thicker, so containment must be sized for it, but it’s the right choice for backbone links, server rooms and Wi-Fi access points, which increasingly need more than Gigabit.
• Fibre is used between buildings, for backbone runs beyond copper’s 100-metre limit, and where electrical isolation matters.

The 100-metre limit is for the whole channel: about 90 metres of fixed cable plus patch cords at each end. We design routes so no run gets close to it.

What the work involves

1. Survey. We walk the site to confirm outlet positions, comms room locations, cable routes and the wall and ceiling construction along each route.
2. Containment. We install trunking, tray, basket or conduit, sized for today’s cable count plus headroom for growth, and kept apart from power cables.
3. Cable installation. We pull cables along the planned routes, respecting bend radius and pulling tension, with no over-tightened cable ties that crush the pairs.
4. Termination. We terminate cables onto patch panels and outlets using a consistent wiring standard throughout.
5. Labelling. Every cable end gets a durable label matching a port schedule that records the room, panel, port and purpose of each outlet.
6. Certification testing. Every run is tested with a calibrated certification tester, and the results are saved per cable.
7. Handover. We hand over as-built drawings, the port schedule and the full test report.

What’s included and what’s not

Typical timelines and what drives cost

A single-floor office of 20 to 30 outlets typically takes two to four working days, including testing. Larger sites, multi-floor risers and buildings with solid walls take longer. Cost is driven by outlet count, run lengths, containment type, wall and ceiling construction, and category: Cat6A cable and components cost more than Cat6. Containment routing, not cable, is usually the larger cost driver, which is why we quote after a walkthrough rather than per point over the phone.

Equipment typically used

Cat6 or Cat6A twisted-pair cable, low-smoke zero-halogen sheathing where fire safety requires it, keystone or punch-down patch panels, faceplates and outlets, PVC or metal containment chosen for the environment, cable management in the rack, and fibre with suitable connectors for backbone links. Category, sheath and containment choices are confirmed before work starts and written into the quote. We never substitute a lower specification without agreement.

Common mistakes we see

The most common problem in existing sites is cabling with no labels or port schedule, so every later fault takes longer than it should. The second is containment sized only for today, so adding cables means a second project. The third is skipping certification testing to save cost: a marginal run isn’t found until it causes intermittent problems under real traffic, usually months later. We also often find Cat6 cable on Cat5e connectors, which quietly limits the whole run to the lower category, and data cables bundled tightly alongside power cables, which invites interference.
