Passive infrastructure,
correct to the last port
Design, installation and certification testing of copper and fibre structured cabling — to TIA‑568 and ISO/IEC 11801.
What we do
The whole passive layer, from the first core drill to the last label on the patch panel. We supply the active equipment too if you want it, and configure and commission it properly, with an experienced team.
Structured copper cabling
Horizontal and vertical runs in Cat6 and Cat6A, keystone and patch-panel termination, and a channel test on every port.
Details and specifications → S-02Fibre optics
Single-mode and multimode backbones, fusion splicing, pigtails and ODFs, with the power budget calculated before anything is pulled.
Details and specifications → S-03Racks and cable management
Floor-standing and wall-mounted racks, unit layout, horizontal and vertical cable management, earthing and in-rack ventilation.
Details and specifications → S-04Cable pathways
Tray, ladder, trunking, conduit and floor systems — respecting the minimum bend radius and keeping power and data apart.
Details and specifications → S-05Certification testing
Permanent Link and Channel testing on a calibrated tester, and a report you can hand to the client and the supervising engineer.
Details and specifications → S-06Documentation and maintenance
As-built drawings, standards-based labelling, a port schedule and an annual support contract.
Details and specifications →Five stages, in this order
The order is not negotiable; every project that has gone wrong skipped one of them.
Site visit and survey
Measuring pathways, reviewing the rack location, existing power and earthing.
1–3 daysDesign and BOQ
Route drawings, rack layout and an itemised bill of materials with named brands.
3–7 daysInstallation
Pathways, cable pulling, termination and rack assembly by a fixed crew.
Scale-dependentTesting and certification
Every port tested individually; any link without adequate margin is corrected.
1–4 daysHandover and warranty
As-built drawings, the full test report, and the start of the system warranty.
10-year coverWhat we hold ourselves to on paper
These are not just names; each row decides something specific in your project.
| Standard | Subject | Where it shows up in your project |
|---|---|---|
| TIA-568.2-D | Balanced twisted-pair cabling | Choosing Cat6A, the NEXT and return-loss limits, and the basis for a passing test. |
| ISO/IEC 11801-1 | Generic cabling for premises | The overall architecture of a building network and Class EA / F. |
| TIA-569-E | Pathways and spaces | Tray and trunking sizing, permitted fill, and equipment-room conditions. |
| TIA-606-C | Administration and labelling | The label format for every port and the structure of the documentation set. |
| ISO/IEC 14763-3 | Optical fibre testing | OTDR method, power budget and the loss limit for each splice. |

Get an initial estimate
A port count and an approximate floor area are enough; we send the first estimate the same day and the site survey is free.
