Data network cabling

A reliable, well-structured data network is the backbone of any modern business. Poor cabling – whether badly installed, under-specified, or simply outdated – creates bottlenecks, reliability issues, and headaches that are difficult to trace and expensive to fix. Getting it right from the start, or bringing an existing setup up to standard, makes a real difference to how smoothly a business runs day to day.

Leonard's Electrics design and install data network cabling solutions for businesses across Jersey. We take the time to understand how your organisation works, what your current infrastructure looks like, and where you're headed – so the solution we deliver is built not just for today, but for the years ahead.

What we install and support

We work across the full range of structured cabling and network infrastructure, including:

  • Structured cabling – Cat5e, Cat6, and Cat6a installations designed and installed to industry standards, clearly labelled and documented for easy management.
  • Fibre optic cabling – Installation, fusion splicing, fault finding, power meter testing, and OTDR testing for high-speed, long-distance connections.
  • Wireless networks – Access point installation and configuration for reliable wireless coverage throughout your premises.
  • Server room infrastructure – Rack installation, switch and blade server cabling, patch panels, and all associated cable management.
  • Telephone systems – New installations, upgrades, and moves, adds and changes to keep your communications running smoothly.
  • UPS supply and installation – Uninterruptible power supply systems with bypass switching, protecting critical equipment from power disruption.
  • PA systems and AV – PA installation, flat screen and display mounting, and PC-based signage solutions.
