CORETX own network is constructed with resilient dark fibre and wavelength services, as this provides the correct level of control, capacity and scalability required by a modern connectivity carrier.

We have a great deal of experience designing, deploying, owning and operating fibre optic networks for carriers, our network is constructed from 100% privately owned dark fibre and we have experience with new build scenarios.

This core competency allows CORETX to plan, deliver and manage very high performance Dark Fibre and Wavelength services directly for our customers. We have agreements in place with Metro, National and International fibre operators, allowing us to provide solutions which span the UK, the Atlantic and the Globe, matching the correct partner to the specific customer need.

  • Access to widest range of deployed Dark Fibre capacity
  • Only carrier to offer new dark fibre route construction
  • Unlock data centre potential by connecting to the CORETX network
  • DWDM Wavelength services offered at multiple core sites
  • Solutions suitable for both Data Centres and business premises
  • Highly experienced support and provisioning personnel
Dark Fibre footprint

CORETX can offer Dark Fibre connectivity in multiple locations across the UK and internationally, this includes the provision of existing infrastructure as well as the construction of entirely new fibre routes. Having operated carrier grade networks based on dark fibre Infrastructure for many years, CORETX is very well versed with the technology required, the advantages it can offer and the potential pitfalls which need to be recognised, mitigated and avoided.

CORETX is entirely carrier neutral, we are able to work with the widest range of fibre providers, we have first-hand experience of commissioning, planning digging and deploying our own multi-core fibre optic cabling between new locations and can bring this experience to bear for our customers.

What is Dark Fibre?

Dark Fibre simply refers to a fibre optic cable which has been deployed, normally buried under the ground or sea, but which has not yet been commissioned, termed 'lighting' the fibre. Digging cable routes across cities, countries and even continents is a costly, time consuming and disruptive task, thus, fibre optic cables are deployed in bundles, tens even hundreds of fibre optic cables, encapsulated in a single trunk and buried under ground at the same time.

This potential capacity only becomes useful, when a carrier installs suitable equipment and establishes the correct connections to create an end to end service.
