The air blown fiber (ABF) method is a modern technique where a jetting machine uses compressed air to install a lightweight fiber optic microcable into a pre-installed microduct. The primary advantage of this method is the reduction in tensile stress on the delicate fiber optic cable during installation, which minimizes the risk of damage. It's also significantly faster for long distances, more cost-effective due to less labor and smaller equipment, and provides future-proof scalability as you can install empty ducts and blow in more fibers later as demand increases.
