Air-blown fiber optic cable installation is a highly efficient method used for laying long-distance fiber optic networks. This technique, also known as air-assisted cable installation, offers significant advantages such as reduced installation time, minimized disruption, and flexibility in network.

Normally, micro-duct cables are jetted into an appropriately sized micro-duct. To insure that the jetting operation can be done efficiently, micro-duct should be selected to have some space between its inner diameter (ID) and the cable it contains. The recommended fill ratio has been empirically det
