Description
The 4-48F Mini Air blown Fiber optical cable, Also be called ABF cable. It consists of 4-48x 250um bare fibers, Those color-coded bare fibers covered by a layer of PE outer sheath.
OMC’s ABF Cable is with small diameter, lightweight, highly flexibility and proper stiffness. The fibres are coated with a soft acrylate resin which provides excellent dimensional and thermal stability to cushion the fibres, in addition, the resin can be easily stripped in connecting the fibres. The outer sheath is a thermoplastic that is of low friction. The surface of the sheath is designed with special grooves, compared to the surface of the traditional optical fibre cable, it provides not only the high level of mechanical protection, but also the perfect blowing performance.

Application：
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.
The cable can be used as the drop cable of distribution segments in FTTH networks and can be laid by air blowing to connect the branch point with the access point for subscribers. The cable is also applicable in backbone networks , metropolitan area networks and access networks
Air Blowing cable technology is a new way to make significant improvements in traditional fiber optic systems, facilitating the rapid adoption of fiber optic networks and providing users with a flexible, secure, cost-effective cabling system.
The blowing system consists of micro-tubes (single micro-tubes and micro-tubes), micro-cables, fittings and air blowing equipment.
