CRALEY Fibre™

From Source to Tap - There's a ready-made conduit suitable for deploying fibre optic communication cables
CRALEY Fibre™ is a patented ‘in-pipe’ solution designed specifically for deploying fibre optic communication cables inside new or existing pipeline infrastructure.
The simple but effective solution is based on two key components:
-
Specially designed pipeline entry and exit fittings: the Final Fittings, and
-
A special purpose small-bore hollow tube that runs inside the pipeline between the fittings: the Messenger Pipe™

Why use CRALEY Fibre™ ?
Using CRALEY Fibre™ for fibre optic deployment makes perfect sense, as the infrastructure is already there. This existing infrastructure provides a ready-made conduit in which a fibre cable can be installed at a faster and more cost-effective way, when compared to traditional methodologies.
Using CRALEY Fibre™ consistently provides:
-
A faster deployment method
-
Reduced civil works
-
Less neighbourhood disruption
-
Less traffic management and disruption
-
Cost reductions
-
Minimal or no requirement for wayleaves and easement access
One of the key design concepts with CRALEY Fibre™ is the hollow Messenger Pipe™, which is a deliberate engineering consideration, and make the finished installation fully future-proofed against changing fibre technology and/or fibre count requirements. Once the Messenger Pipe™ installation has been completed, the fibre cable can be inserted using standard fibre-blowing techniques, installing just as many fibres as is required at that point. Should the requirement change, or fibre cable technology has moved on, the cable can simply be removed and a new cable blown-in at any time.
