It delivers the best fiber solution for backbone, specialty, Fiber-To-The-Desk (FTTD) and Fiber-To-The-Home (FTTH) applications
Air Blowing Micro fiber Optic Cable system for underground duct networks. The Air Blowing Micro fiber Optic Cable product line is a complete solution with designs suitable for many applications and needs from backbone networks to FTTx. Whether the need is for high fiber density or small cable diameter, the Micro fIBER range has the solution. Designs are always based on minimal cable and duct diameters for cost effective installation and materials.
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
This 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.
Fibre optic cable is an advanced type of network cable, offering significantly improved performance in terms of bandwidth and data carrying than traditional metal conductor versions.

Fibre optic cables are commonly found today in higher-end internet, phone and TV applications. They’re also used in many other areas of the home and workplace use, including in decor applications – fibre optic Christmas trees, for example, are not at all uncommon now.
The ability of optical fibre cable to save a great deal of space over bulkier types of traditional cabling has also made them a popular choice for numerous lighting and safety features in modern cars. They’re widely used in many other demanding professional fields too, including in a great many medical applications, for detailed mechanical inspections, and as sensors for monitoring and controlling the flow of various sorts of electrical currents, sounds and chemicals.
FAQ – Air‑Blown Micro Fiber Optical Cable
What is the difference between air‑blown micro fiber cable and traditional fiber optic cable?
Air‑blown micro fiber cables are ultra‑light and small‑diameter fibers designed for pneumatic installation through microducts using compressed air. Traditional cables require manual pulling and higher tensile force. Air‑blown designs allow fast, scalable installation with minimal mechanical stress and easy future upgrades.
What is an air‑blown micro fiber optical cable?
An air‑blown micro fiber cable consists of miniature loose tubes or bundled fibers enclosed in a low‑friction HDPE sheath optimized for air‑jet deployment inside microducts. It enables quick network extension without civil rework, ideal for FTTH, FTTB, and access fiber networks.
How does the air‑blowing installation method work?
Compressed air is injected into the microduct, creating airflow that propels the lightweight micro cable along its length. The low surface friction and aerodynamic design help reach several hundred meters to 1 km per blow without mechanical pulling or damage to fibers.
What are the typical structures and specifications of air‑blown fiber cables?
They feature 2‑24 fibers per micro‑unit, gel‑filled or dry tubes, water‑blocking yarn, and an HDPE or PBT outer sheath. Diameter is typically 5‑10 mm with tensile strength around 80‑150 N and bending radius 10× OD. Fiber types follow ITU‑T G.652.D or G.657.A1/A2 for flexibility.
Which standards regulate air‑blown micro fiber cable performance?
Performance tests comply with IEC 60794‑5‑10 for micro‑duct cables, IEC 60794‑1‑21 for mechanical testing, Telcordia GR‑20 for environmental and bending endurance, and ITU‑T G.657 for bend‑insensitive fiber characteristics, ensuring reliable long‑term deployment in ducts.
What are the main advantages of using air‑blown cables?
Key benefits include faster network expansion, minimal installation labor, reduced duct congestion, and convenient future scalability—new fibers can be blown in when additional capacity is needed without any excavation.
Which air‑blown cable type should I choose?
For short access or indoor drops use 2‑12 core G.657.A2 micro cables. For long outdoor routes or campus networks, select 24‑core G.652.D cables with dry water‑blocking materials. Ensure compliance with IEC 60794‑5‑10 and use compatible microduct sizes (5/3.5 mm, 8/5 mm).
