Structured cabling, fibre backbone, building controls and instrumentation. Lower voltage, higher consequence — a power cable that underperforms trips a breaker, whereas a data cable that underperforms produces intermittent faults nobody can find.
Four families, all available in low smoke zero halogen construction and in riser or plenum grades where the design calls for them.
Cat 6, Cat 6A and Cat 7 horizontal and backbone copper, in U/UTP, F/UTP and S/FTP constructions. For commercial buildings, campuses and mission-critical installations where the cabling has to certify to a channel test, not just pass a continuity check.
Single-mode OS2 and multimode OM3, OM4 and OM5. Loose tube and tight buffered, indoor, outdoor and indoor/outdoor rated, armoured where rodents or mechanical risk demand it. Campus backbone, riser, office trunking and FTTx distribution.
BMS and BAS field wiring, ventilation and damper control, valve actuators, access control and door hardware. Screened and unscreened, in the core counts and conductor sizes the controller manufacturer actually specifies.
Individually screened pairs, collectively screened pairs, or both, for 4–20 mA loops and field instrumentation. The screening arrangement is the specification — getting it wrong shows up as drift and noise long after commissioning.
Certified bus cable for KNX building automation — lighting scenes, blinds, HVAC zoning and room control. Twisted pair with the correct impedance and colour convention, so commissioning tools behave the way the documentation says.
Voice, data and signal transmission cable for internal distribution and riser duty, including multipair backbone for legacy voice and paging systems still in service across large estates.
The numbers that decide whether an installation will certify.
| Category | Bandwidth | Typically supports |
|---|---|---|
| Cat 6 | 250 MHz | 1 Gb/s to 100 m; 10 Gb/s over reduced length |
| Cat 6A | 500 MHz | 10 Gb/s to 100 m — the usual choice for new build |
| Cat 7 | 600 MHz | 10 Gb/s with individually screened pairs |
| Grade | Type | Typical use |
|---|---|---|
| OS2 | Single-mode, 9/125 µm | Campus and inter-building backbone, FTTx, long runs |
| OM3 | Multimode, 50/125 µm laser optimised | 10 Gb/s to 300 m in data centres and risers |
| OM4 | Multimode, 50/125 µm | 10 Gb/s to 550 m; higher rates over shorter spans |
| OM5 | Wideband multimode | Short-wavelength division multiplexing |
Low current cable is the category where substitution does the most damage, because the difference between a certified Cat 6A channel and a cable that merely says Cat 6A on the drum only appears when the installation is tested — by which time it is in the ceiling.
Through our partnership with Amoori Trading LLC we supply internationally certified cable from established manufacturers, named against each line so your consultant can check the datasheet before you order rather than after.
If a specification names a manufacturer we cannot source, we will say so rather than quote an equivalent and let the difference surface at handover.
