Air-blown fiber systems utilize air to propel micro optical fiber cables through pre-existing microducts. This method, also referred to as jetting fiber, provides an effective means of installing fiber optic cables and supports the future growth of fiber optic networks. This design allows the optical cable to possess high fiber density, a small diameter, and a lightweight profile. Additionally, it provides superior fiber protection and flexibility. Air-blown micro cables primarily come in two types: central tube and loose tube layer stranded.
