Data Centre Cabling for Controlled Infrastructure

ACCL provides data centre cabling London businesses can use to connect racks, cabinets, servers, switches, storage and network services through an organised physical infrastructure. We coordinate the route, containment, copper and fibre, termination, testing, labels and records around the operational brief. Delivering a full office fit-out rather than a data centre alone? See our office fit-out technology infrastructure page for the coordinated package.

A new installation may support a dedicated facility, server room, communications room or edge location. Expansion and migration work can also be planned around existing services and agreed maintenance windows. Where the requirement forms part of a wider building network, our structured data cabling service coordinates horizontal links and backbone infrastructure.

What a Data Centre Cabling Project Includes

The scope can include cabinet and patch-panel layouts, Cat6A or other specified copper cabling, single-mode or multimode fibre, overhead or underfloor pathways, containment, equipment cords, fibre enclosures, labelling, testing and handover documents. Requirements are confirmed during survey and design rather than assumed from a generic specification.

We used ACCL for a full WiFi and network install at our Old Street office and are very pleased with the result. They supplied and installed seven Ubiquiti WiFi access points, a UniFi Dream Machine, a 24 port Layer 3 Ubiquiti switch, and ran new Cat6A Leviton cabling with two ports to every AP. The whole job was neat, well planned and done to a very high standard. The coverage across the office is excellent and it looks pretty cool too! Would happily recommend them to anyone needing cabling or network infrastructure done properly.

We've worked with Wayne, David and the ACCL team for a number of years on projects throughout London. One of very few suppliers that we never have to question their proposal on detail or price, everything is clear, transparent and fair. Projects are always completed on time and there are never any costly surprises which we had previously experienced from other suppliers. They all have a vast knowledge on anything fibre optic cabling, copper cabling or wifi. ACCL is now the only data cabling company in our phone book. Highly recommended.

Rack, Cabinet and Patch-Panel Design

Rack layouts should keep patching understandable, preserve service access and allow planned additions. ACCL maps cabinets, patch panels, switch positions, fibre enclosures and cable entry points so that installation and future administration can be coordinated. Existing cabinets can be assessed before reuse; congested or poorly labelled environments may benefit from a separate data cabinet tidy.

Copper and Fibre Backbone Options

Copper cabling

Cat6A is commonly considered for high-performance copper links, but category, shielding, channel length, patching and equipment interfaces must match the application. Copper links are terminated and tested against the agreed cabling specification.

Fibre optic cabling

Fibre can support switch-to-switch, cabinet-to-cabinet and building-backbone connections. Single-mode or multimode selection depends on distance, optics, capacity, loss budget and expansion needs. ACCL can coordinate fibre optic installation, splicing, termination and fibre testing and certification.

Containment, Separation and Airflow Coordination

Cable routes must work with the facility layout. Pathways, bend radius, support, power separation, access, fire stopping and cabinet entry are reviewed before installation. Good routing also avoids unnecessary obstruction around equipment airflow, but cabling design does not replace the facility’s mechanical or environmental design.

Our Data Centre Cabling Process

Survey and design

ACCL records endpoints, cabinets, equipment interfaces, route constraints, operating rules, capacity, resilience requirements and the required handover. The resulting scope identifies assumptions and exclusions before work begins.

Installation and change control

Routes, containment, cable pulls, terminations and patching are sequenced around approved access and maintenance windows. In a live environment, every affected service and dependency should be agreed before a move or change. The objective is controlled delivery that reduces operational risk; no cabling contractor can responsibly promise zero risk or zero downtime.

Testing and handover

Copper and fibre are tested using methods appropriate to the medium and project specification. Labels, schedules, results and other agreed records are assembled for handover.

Working in Live Data Centre Environments

Live-site work requires defined access, permits where applicable, task sequencing, identification of active services, rollback points and communication with the customer’s operational team. Some work can be completed without affecting services; other tasks require an agreed outage or migration window.

If an existing copper route is damaged or failing, use ACCL’s data cabling repair service for fault investigation and repair scope.

Testing, Labelling and Documentation

Installed copper links can be certification-tested to the agreed category and channel or permanent-link requirement. Fibre scope may include inspection, optical-loss testing and OTDR traces where specified. Test equipment and limits are selected for the system; the page does not claim that one tester or test method applies to every link.

Handover can include cable and port identifiers, cabinet and patch-panel references, route or cable schedules, copper results, fibre results, product information and drawings where included in the contract. The BS EN 50600 series for data centre facilities and infrastructure provides useful context, including telecommunications cabling infrastructure. A reference to the series does not claim that ACCL or a customer facility is certified to it.

What Affects Data Centre Cabling Cost?

Cost depends on cabinet count, link quantities, copper category, fibre type and cores, route length, containment, working height, access, out-of-hours work, live-site controls, terminations, testing and required documentation. Existing pathways and cabinets may be reusable only after inspection.

Why Choose ACCL for Data Centre Cabling?

ACCL coordinates cabinets, copper, fibre, containment, testing and handover as one physical-infrastructure package. Relevant project experience includes work for Southampton FC and Thames Tideway. Warranty wording is tied to the products, installer eligibility, registration and terms of any applicable manufacturer scheme rather than presented as a blanket promise.

What our clients think

  • I have been dealing with Wayne at ACCL for some time now, as I was tasked by my employer to refurbish our server cabinets across 30 offices in London. I can’t begin to express how good Wayne and his guys are. They have replaced and refurbished a large number of our server cabinets so far, with no issues, all in a very timely manner.

    They have done a highly professional job, have always kept in contact, and have given us advice/suggestions on what was needed when we weren’t too sure. I would highly recommend using ACCL for any IT/Cabling work.
