A process built around live sites.

  1. 01Survey and designRoutes, cabinets and access checked.

    We review the systems you need to support, cabinet positions, pathways, containment and access rules, then give you an itemised quotation.

  2. 02Installation around your operationsPhased, out of hours where needed.

    Work is planned around your working hours and building rules, in agreed windows, with method statements and risk assessments.

  3. 03Testing and handoverTested, labelled and documented.

    Every link is tested to the agreed specification and labelled. Test results and as-built records are handed over at the end.

Fibre optic installation in Canary Wharf

Commercial fibre optic installation for Canary Wharf towers and Docklands offices

Canary Wharf is built for scale: high-rise towers, multi-floor corporate occupiers, banks, and data-intensive financial operations. Connectivity here has to move large volumes of data reliably across many floors and tenancies. ACCL delivers commercial fibre optic installation throughout Canary Wharf and the wider Docklands, engineered for the bandwidth and resilience these environments demand.Our fibre engineers design and install single-mode and multi-mode fibre backbones, riser and inter-floor links, and campus connectivity between buildings. ACCL already provides structured data cabling in Canary Wharf, so fibre is delivered by a team that knows the estate and its access requirements.

Why Canary Wharf banks and corporates choose fibre

In a high-rise, high-density financial district, fibre is the natural backbone choice:
  • Multi-floor and riser distribution: fibre carries high bandwidth vertically through towers far more efficiently than copper alone.
  • Capacity for data-heavy operations: single-mode fibre supports 10 Gigabit and beyond for trading, analytics, and large corporate networks.
  • Campus and inter-building links: fibre connects multiple buildings across the estate with consistent, high-speed performance.
  • Resilience for financial occupiers: tested and certified links reduce the outage risk that banks and corporates cannot accept.
  • Future-ready infrastructure: a fibre backbone scales with demand without re-cabling, protecting the investment as occupancy grows.

Engineered for towers, tested and certified

Testing and certification are agreed to suit the installed fibre system and project specification. Eligible manufacturer systems can be registered for a 25-year warranty only where the approved components, installer, testing, documentation and registration conditions are met. ACCL holds ISO 9001, ISO 14001 and ISO 45001 certification, which are important credentials for the managed buildings and corporate procurement processes common across the Wharf. For large multi-tenant towers we also design passive optical networks, which reduce the number of powered comms rooms needed across many floors. And if a fault ever occurs, our fibre optic repair team provides rapid response across Docklands.

Fibre backbone capacity for high-density towers

Why Canary Wharf’s towers need a fibre-first backbone

Canary Wharf’s high-rise towers carry some of the highest data demands in London: large floor plates, multiple tenancies per building and data-intensive trading and analytics operations. Copper alone cannot move that volume of data vertically through a tower at these distances; fibre is the backbone technology that scales.

Where we design fibre backbones in the estate

We deliver fibre for:
  • Trading floors and dealing rooms with resilient fibre uplinks to core switches and data centres.
  • Multi-floor riser backbones carrying high bandwidth vertically through towers to every tenancy.
  • Campus and inter-building links connecting multiple towers across the estate.
Structured copper cabling for the desk-level network in these same towers is covered by our structured data cabling service in Canary Wharf: fibre and copper are designed together as one backbone-to-desk system.

Managed towers and multi-tenant buildings

Canary Wharf’s managed towers present specific requirements around access, landlord approval, riser usage and programme coordination. We are experienced with these processes and plan installations around building management and tenant operations, including phased and out-of-hours works.

  • Riser and inter-floor fibre planned and installed within building management requirements.
  • Passive optical networks for large multi-tenant towers, reducing powered comms room requirements across many floors.
  • Neat patching and clear labelling for straightforward MACs as tenancies change.

ISO 9001 and ISO 45001 certification supports the quality, health, safety and procurement requirements relevant to Canary Wharf’s managed estate.

Building types and installation considerations

Canary Wharf’s high-rise towers and multi-tenant estate present specific requirements for fibre routing, riser access and containment that our engineers plan carefully for every project.
  • High-rise towers with multiple comms rooms, risers, and critical backbone dependencies across many floors.
  • Managed buildings with strict access, security and landlord requirements.
  • Large corporate campuses requiring inter-building fibre links across the estate.
Every installation is fully tested, labelled and documented, giving your IT team clear, audit-ready records.

Technologies, standards and future-readiness

Our installations use proven components and follow industry standards to ensure performance today and headroom for tomorrow.
  • Multimode and singlemode fibre optic cabling for high-speed backbone and inter-floor links.
  • Structured cabling to support modern Wi-Fi, IP telephony, CCTV, access control and building management systems.
  • Design, installation and testing against the standards and acceptance criteria identified in the project specification, with documented results for the links included in the agreed test scope.
This standards-based approach makes it easier to scale, upgrade and integrate new technologies over time.

Frequently Asked Questions: Fibre Optic Installation Canary Wharf

Do you cover Canary Wharf and the wider Docklands?

Yes. We deliver fibre optic installation across Canary Wharf, the surrounding towers, and the wider Docklands and E14 area.

Can you work in managed multi-tenant towers?

Yes. We are experienced with the access, security, and landlord requirements of managed buildings, and plan works around building management and tenant operations.

Can you install fibre backbones across multiple floors?

Yes. Riser and inter-floor fibre backbones are a core part of our work in high-rise environments, along with inter-building campus links across the Canary Wharf estate.

Is the fibre installation tested and certified?

Testing and certification are specified for the installed fibre system and agreed scope. Eligible manufacturer systems can be registered for a 25-year warranty where all programme conditions are met.

Do you provide out-of-hours installation?

Yes. We routinely schedule works out-of-hours and in phases to avoid disruption to corporate and financial operations.

Do you also provide structured cabling in Canary Wharf?

Yes. Fibre is part of our wider structured data cabling service in Canary Wharf, so backbone fibre and copper distribution can be delivered together by the same team.
