Fibre Blowing Machines

TELECOMS

Through our partnership with Jetting, we supply a range of fibre blowing machines for the local telecoms market. Fibre networks are becoming more prominent for both business and domestic use. With suppliers now providing FTTH (Fibre to the Home) thus replacing existing copper infrastructure such as telephone wires and coaxial cables. Installing such fibre networks requires the need of machines called fibre blowing machines, which allow for a much faster installation of fibre optic cable over large distances rather than the traditional methods of pulling the cable through cable ducts.

 

What is Fibre Blowing?

Fibre cable blowing is one of the last stages in fibre projects. Fibre blowing or cable jetting is the process of blowing fibre optic cable while simultaneously pushing it through any sized duct. This is possible by using compressed air. The benefits of fibre blowing include: installing the cable along longer distances, it is less resistant to bends and undulations, there are fewer forces exerted on the cable, minimised set-up times and less manpower. Contrary to popular industry belief, fibre blowing does in fact allow the blowing of larger sized diameter cables. Fibre blowing is an efficient way to install fibre optic cables.

 

Jetting Fibre Blowing Machines

Established in Sweden since 2008, with a history in mechanical and industrial engineering, Jetting have developed and manufactured a series of fibre blowing machines which are reliable, robust and easy to handle. Each machine can be deployed on site within minutes ranging from handheld machines to larger cable applications with the capability of blowing fibre into ducts of varying diameter sizes. Fibre blowing is made easy with Jetting Fibre Blowing Machines.

TriggAIR

TriggAIR is a robust, handheld fibre blowing machine that guides and feeds fibre cable into micro ducts by using an electric motor and with optional compressed air to reduce friction. It has an adjustable mechanical clutch, that limits the pushing force on the fibre cable to avoid damage in case of a sudden stop. TriggAIR has an air block with a maximum allowable air pressure of 16 bar and built-in duct clamps for 5.0 and 7.0mm ducts. It is fitted with a Li-ion 12V battery that powers the motor and an operated drive wheel that when combined with compressed air it installs fibre cables from 1.0 – 3.0mm at a speed of 0 to 150m/min.

TriggAIR has a built-in digital LCD Display that displays speed and distance as well as a manometer to provide full control of the fibre blowing process. It is controlled by a trigger, which can be locked in at a preferred speed and also has a reverse function to pull the cable out.

  • Automatic input of temperature, humidity and the exact position by GPS.
  • Monitoring every 1.0 m:
    • Air pressure
    • Speed
    • Distance
    • Pushing force
  • Parameters are presented live on the tablet giving the user a full overview of the process.
  • Automatic safety shutdown if optimal pushing force is exceeded.
  • A protocol in PDF format can be saved and can be sent to the network owner.
  • Logs the type of cable and Duct used.
  • Integrated GPS to locate the exact position of the cable installation via Google Maps
  • Integrated 4G and SIM card slot.
  • Supports all cloud services such as Dropbox, OneDrive, Google Drive and Apple iCloud
