Air-blown optical cable includes

Air-blown optical cable consists of microducts, optical fiber microcables, a blowing apparatus, termination cabinets, and connecting/terminating hardware.

Core Components

Microducts: These are small, flexible plastic tubes (typically HDPE) with low-friction linings that allow fiber to glide through easily. Microducts are installed along the planned route first, either underground or overhead, and can be bundled in groups of 7, 12, or 24 to provide multiple pathways for current and future fiber deployment. Optical Fiber Microcables: Lightweight, high-fiber-count cables designed specifically for air-blown installation.

They have a small outer diameter (usually 3–8 mm), low-friction sheath, and high tensile strength to withstand the blowing process without damage. These microcables can be loose tube or ribbon designs depending on the application. Blowing Apparatus: A specialized machine that uses compressed air (typically 8–15 bar) to propel the microcables through the microducts.

The airflow creates a cushion that reduces friction and allows the fiber to travel long distances efficiently, often hundreds of meters in a single run. Termination Cabinets and Distribution Hardware: Cabinets are installed at duct branches and endpoints to manage fiber distribution, splicing, and connections. They ensure organized routing and facilitate future network expansions.

Connecting/

Terminating Hardware: Includes optical connectors, splicing equipment, and other accessories required to interface the blown fibers with network devices or other fiber segments. These components are compatible with standard optical connectors and help minimize optical loss. AdvantagesAir-blown optical cable systems allow flexible, scalable deployment, enabling fibers to be installed as needed without pre-installing all fibers.

This reduces initial investment, simplifies upgrades, and minimizes splicing points, enhancing overall network performance. They are ideal for FTTx, data centers, campuses, and high-density urban environments where space is limited and future expansion is anticipated.
