Air blown fiber systems use air to blow micro optical fiber cables through pre-installed microducts.

Air blowing fiber, also known as jetting fiber, is an efficient way to install fiber optic cable and facilitates future expansion of optical fiber networks. Fibers can be installed in areas that are hard to reach or that have limited access. Air Blown Fiber is also recommended for environments where there will be many changes and additions to the network. It also allows for duct installation before you know how much fiber is actually required, and so eliminates the need to install dark fibers. It also reduces splicing and interconnection points so optical loss is minimized and system performance is enhanced.
