Fibre Backbone & Long-Run Cabling Installation
OM4 multimode and single-mode fibre backbone installation for large warehouses, distribution centres, industrial sites, and multi-building campuses — OTDR-certified and EMI-immune.
Copper structured cabling has a hard limit: 90 metres for the horizontal run between the distribution frame and the outlet. On any site larger than a small office — a warehouse, a large factory, a campus of interconnected buildings — you will exceed this limit. Fibre optic cable is the correct solution for these long-run backbone connections. It carries 10Gbps (or faster) over distances of hundreds or thousands of metres, is completely immune to electromagnetic interference, and provides a future-proof backbone that your copper distribution can plug into at every IDF location.
We install fibre backbone cabling as part of larger warehouse and industrial projects, and as standalone backbone upgrades where sites have outgrown their existing copper infrastructure or where EMI issues are causing reliability problems on long copper runs.

OM4 multimode backbone
The standard choice for intra-building backbone connections in warehouses and large industrial sites. Supports 10Gbps over 400m, 40Gbps over 150m. Cost-effective and appropriate for most single-site applications.
OS2 single-mode fibre
For inter-building connections, campus networks, or any application where future distance or bandwidth requirements may exceed multimode limits. Supports 10Gbps over kilometres and is future-proof for 40/100Gbps upgrades.
Aerial fibre routes
Overhead fibre routes between buildings using armoured aerial cable — a practical solution for short campus crossings where underground ducting is not practical.
Underground ducted fibre
HDPE duct installation with blown or pulled fibre cable for underground inter-building routes. Designed to allow future cable replacement or additional fibre installation without excavation.
Fibre patch panel installation
LC, SC, or appropriate connector type patch panels installed in MDF and IDF cabinets, with proper cable management, slack storage loops, and labelling.
OTDR testing and certification
Every fibre run tested with an OTDR to confirm optical loss meets specification. OTDR traces retained as part of the certification record and included in the handover documentation pack.
Technical guidance
Choosing the Right Fibre Standard
| Standard | 10 Gbps distance | 40 Gbps distance | Best for |
|---|---|---|---|
| OM3 | 300m | 100m | Existing older installations |
| OM4 | 400m | 150m | New warehouse backbone installs |
| OM5 | 400m+ | 150m+ | High-density / wideband WDM applications |
| OS2 (single-mode) | Kilometres | Kilometres | Multi-building / campus / long runs |
For most new warehouse and distribution centre backbone installations, OM4 multimode fibre is our standard recommendation — it provides 10Gbps up to 400 metres at a cost significantly below single-mode, and 10Gbps is sufficient for all but the most demanding current workloads. We will recommend OS2 single-mode where run lengths exceed OM4 limits or where a campus/multi-building topology is in scope.
Common questions
Fibre Backbone FAQs
When do I need fibre instead of copper cabling?
Fibre is required when cable runs exceed the 90-metre horizontal limit of copper structured cabling, when you need immunity from electromagnetic interference (EMI) in industrial environments, or when you need to connect buildings across a campus. For warehouse and distribution centre backbones — connecting the main comms room to intermediate distribution frames across a large floor — fibre is almost always the correct solution.
What is the difference between multimode and single-mode fibre?
Multimode fibre (typically OM4 or OM5) supports 10Gbps over distances up to 400 metres (OM4) and is the standard choice for inter-building or intra-building backbone connections within a single site. Single-mode fibre supports 10Gbps and beyond over distances of kilometres, making it the correct choice for multi-site connections, campus networks, or any connection where future distance or bandwidth requirements may grow significantly.
Do you install underground ducted fibre between buildings?
Yes. For campus and multi-building sites, we install underground duct systems (HDPE duct or armoured cable direct-buried where appropriate) to carry fibre between buildings. This work is planned as part of the overall site design and includes appropriate depth, route marking, and documentation.
How is fibre optic cabling tested and certified?
Every fibre run we install is tested using an Optical Time Domain Reflectometer (OTDR). The OTDR measures optical loss, identifies splice points, and produces a trace that serves as the certification record for the fibre link. This test confirms the installation meets the specified loss budget and provides a baseline for future fault diagnosis.
Can you terminate fibre into existing cabinets and patch panels?
Yes. We can install new fibre runs and terminate into existing cabinets and patch panels, or supply new fibre patch panels as part of the project. We work with LC, SC, and other common connector types and can match the fibre type and connector standard already in use on your site.
How long does a fibre backbone installation take?
A straightforward internal backbone installation — pulling fibre from an MDF to two or three IDF positions in a large warehouse — typically takes 2–4 days including termination and testing. Underground inter-building routes are longer in programme depending on distance, ground conditions, and any civils work required.
