What is Blown Fibre?
Blown fibre optic is a cabling solution using glass fibre optic cables, blown through a ducting pipe. The main ducting pipe can have up to 19 micro ducts contained within it. A Coated “blow able” optical fibre is blown through a micro duct using compressed air. Carried by viscous drag, the fibres are lifted into the airstream and away from the wall of the micro duct, eliminating friction even around the tightest bends. One Fibre optic strand can carry 10 gigabytes of data every second or over 3000 telephone conversations.
The benefits of blown fibre are simplified planning, cost effective solution, speed of installation, and is greener solution compared to copper cable.
The ground works to install the network only has to be done once. When the waterproof ducting is in place the network can be expanded by simply blowing more fibres, or blowing the old fibre out and bigger fibres in. We are currently blowing up to 288 fibres into a single duct, but we expect to be blowing over 1000 fibres within twelve months.
