Blown fibre installs use glass fibre optic cables, blown with a combination of air and mechanical pushing through a ducting pipe. This provides you with a cost-effective, scalable and easy-to-install solution compared to conventional cabling.
Also known as a duct/subduct, the tubes are installed empty, ready for your engineer to install the fibre. This bit of the installation can be done by non-specialised staff and requires very little training.
At this stage, the minimum bend radius needs to be observed, to ensure damaging/performance-constraining kinks are not introduced.
Installing Fibre Cables
This is the part that requires your skilled engineer to operate specialised machinery. This machinery uses filtered compressed-air to install a bundle of blown fibre into the pre-installed tube.
Future-proof: once your ducts/subduct are installed, new fibres are easy to install as and when your requirements change in the future.
It is easy to replace or repair your damaged fibre tubes by using simple push-fit couplings.
As cables are lightweight, easy to handle and mechanically protected by high strength ducting that resists kinking, trapping and twisting. You do not need to consider any additional protection.
You can interrupt multiple bundles midway, without having to worry about disturbing live fibre in other tubes within the bundle.
Installation is neat, tidy and quick. Cables are installed to a specified length, so you will not experience messy coils of slack left over.
Empty blown-fibre ducts require no special handling. You can quickly blow fibre into the tube.
Fibres are contained within a soft inner layer which cushions the fibres. An outer harder layer protects the fibre from damage and a low friction layer helps to improve blowing distance.
Blown Fibre Tube Distribution Closures
With the widespread adoption of blown fibre and cable systems which use multiple micro duct bundles, tube distribution closures have become widespread. These can create an in-line micro duct track joint or, more commonly, branch off individual micro ducts to different destinations. Instead of fibre jointing occurring in the closure, individual micro ducts are joined together by purpose-made push fit connectors that are designed to be watertight.
