Jetting V3 – The Ultimate Fiber Blowing Machine

The Jetting V3
Discover the next level of fiber installation – the Jetting V3 takes fiber blowing to new heights with power and precision. Designed to handle everything from smaller projects to demanding duct routes, it combines advanced technology with user-friendly operation. In this newsletter, we highlight what makes the V3 unique, and take a closer look at three important installation methods: Floating, Subducting and Push/Pull Rod.
Why V3 Stands Out in Fiber Blowing
- Powerful and precise – combining high force with efficient speed
- Wide range – suitable for both microcables and larger fiber cables
- Operator control – smooth joystick handling and digital feedback
- Lightweight yet durable – anodized aluminum construction
- Multi-functional – adaptable for different installation methods and project requirements
Floating – Extended Distances with Water Power
What is Floating?
Floating is an installation method that uses water instead of air to propel the cable through the duct. The water flow reduces friction and turbulence, creating smooth, consistent movement of the cable.
Benefits of Floating with V3
- Enables very long installation distances – up to 10 km (≈ 6.2 miles) in a single run
- Reduces friction – the cable “floats” through the duct with minimal resistance
- Provides higher reliability in complex duct routes with curves and long spans
When to Use Floating
- For extra-long routes where air blowing alone is not sufficient
- In ducts with multiple bends or irregular paths
- When minimal mechanical pressure on the cable is required
Subducting – Multiple Microducts in One Installation
What is Subducting?
Subducting is the process of installing several microducts inside a larger duct. Instead of pulling in just one fiber cable, you prepare the duct system for multiple future fiber installations by placing smaller ducts within the main duct.
Benefits of Subducting with V3
- Increases network flexibility – multiple microducts can be blown into a single larger duct, enabling future upgrades without new civil works
- Efficient use of space – optimizes existing duct infrastructure by maximizing capacity
- Compatible with different duct configurations – for example, 7 × 7/3.5 mm or 4 × 14/10 mm subducts inside a 50 mm duct
- Precise handling – V3 provides strong and controlled pushing force, ensuring the microduct bundle is installed safely and efficiently
When to Use Subducting
- At the start of a new network project where future scalability is important
- In backbone or distribution routes that may later serve multiple customers or areas
- When operators want to minimize future digging and installation costs by preparing the network in advance
Push/Pull Rod – Flexible Installation Support
What is Push/Pull Rod?
With this method, a fiberglass rod is pushed or pulled through the duct, creating a pathway for the fiber cable. It can also be used to install a pull rope, which later helps draw the cable through the duct. The V3 can power the rod both forwards and in reverse, making it an effective support tool for installation.
Benefits of Using Push/Pull Rod with V3
- Provides flexibility in situations where air or floating is not practical
- Ensures precise control of rod movement with the joystick interface
- Useful for preparing ducts by installing a pull rope before cable blowing or pulling
- Effective in ducts with bends, obstacles, or conditions that limit traditional blowing methods
Best Practice Tips
- Select the correct rod diameter and stiffness for the duct route
- Use lubrication to reduce friction and extend range
- Operate the V3 in forward/reverse modes as required for the project
- Combine with other installation methods when ducts are particularly long or challenging
