What Is an Air Blown Fiber Unit?
An air blown fiber unit is a lightweight, miniaturized optical cable designed to be installed into pre-existing ducts using compressed air and specialized blowing machines. Unlike traditional heavy cables, these units are flexible and compact, allowing network operators to deploy high-density fiber connections without the need for extensive civil works or trenching.
Flexible Network Expansion
Air blown fiber units allow you to add capacity to existing infrastructure simply by blowing new micro-cables into empty ducts. This significantly reduces deployment time and lowers your overall capital expenditure compared to pulling traditional cables.
High Density in Limited Space
These units offer exceptional fiber density within a small footprint. For procurement managers dealing with congested urban ducts, this means you can maximize bandwidth capacity per conduit, future-proofing your network against growing data demands.
Quality Standards in Air Blown Fiber Manufacturing
At Shenzhen Guangtong Optical Co., Ltd, our manufacturing process for air blown fiber units adheres to strict ISO 9000 quality management systems. We ensure that every component, from the optical fibers to the outer sheath, meets rigorous international standards for durability and performance.
Advanced Production Equipment
We utilize state-of-the-art SZ stranding and extrusion lines specifically calibrated for micro-cables. This ensures consistent outer diameter (OD) tolerances, which is critical for successful air blowing operations.
Rigorous Testing Protocols
Every batch undergoes strict testing for tensile strength, crush resistance, and temperature cycling. Our quality control guarantees that air blown fiber units will withstand the mechanical stresses of installation and long-term underground deployment.
EU Compliance & Safety
Our materials comply with European Union directives and global environmental regulations. Procuring from GT-Optical ensures you receive products that meet international safety and environmental standards, simplifying your compliance workflow.
How to Choose the Right Air Blown Fiber Unit
Selecting the appropriate air blown fiber unit requires balancing technical specifications with your specific deployment environment. Whether you are building a FTTH network or a metropolitan area network, understanding key parameters helps mitigate risk and ensures optimal signal transmission.
Key Selection Criteria
- Diameter and Flexibility: Smaller diameters (e.g., 1.5mm to 3.0mm) allow for higher packing density in ducts but require careful handling. Choose based on your available duct space and blowing distance requirements.
- Fiber Type: Select between G.652.D (standard single-mode) for general access networks or G.657.A/B (bend-insensitive) for complex indoor or last-meter installations where tight bends are common.
- Jelly Fill vs. Dry Construction: Gel-filled units offer superior moisture protection for direct burial, while dry construction units are easier to splice and terminate, reducing your operational maintenance costs over time.
- Tensile Strength: Ensure the unit has adequate aramid yarn reinforcement if you anticipate long-distance blowing runs or harsh terrain conditions during installation.
Procurement Decision Checklist for Air Blown Fiber
Before finalizing your purchase order, use this checklist to verify that the supplier and product meet your project's technical and logistical needs. This structured approach minimizes procurement errors and ensures supply chain reliability.
Technical Verification
Confirm attenuation values match your link budget calculations.
Verify outer diameter tolerance is within +/- 0.1mm for smooth blowing.
Check operating temperature range suits your local climate conditions.
Supplier Capability
Ensure the manufacturer has proven experience with air blown fiber production.
Validate lead times align with your project deployment schedule.
Request samples for pilot testing before committing to bulk orders.
Common Problems in Air Blown Fiber Deployment
Even with high-quality materials, deployment challenges can arise. Understanding common pitfalls allows you to plan mitigations effectively, avoiding costly delays and material waste during your network rollout.
Blowing Difficulties
Issue: Cable gets stuck in ducts.
Solution: Ensure ducts are clean and free of debris. Use lubricants if recommended and verify that the blowing machine pressure is set correctly for the cable's tensile strength.
Microbending Losses
Issue: Signal attenuation increases after installation.
Solution: Select bend-insensitive fibers (G.657) if the route involves tight curves. Proper cushioning in the cable design also protects against external pressure points.
Moisture Ingress
Issue: Water enters the cable core over time.
Solution: Use gel-filled units for outdoor direct burial or employ proper sealing techniques at termination points to maintain the integrity of the fiber optic link.

Frequently Asked Questions About Air Blown Fiber Units
Get answers to the most common technical and commercial questions regarding air blown fiber units and their implementation in modern telecommunication networks.
What is the maximum blowing distance for air blown fiber units?
Typically, air blown fiber units can be deployed over distances ranging from 500 meters to over 2 kilometers in a single run, depending on duct conditions, cable diameter, and equipment capabilities. Our units are engineered for long-distance efficiency to reduce the number of joint points required.
Can I install air blown fiber units into existing ducts?
Yes, this is the primary advantage of air blown fiber. They are designed to be blown into spare capacity within existing sub-ducts. This allows you to upgrade your network capacity without the expense and disruption of laying new conduits.
What is the typical lifespan of an air blown fiber cable?
When installed correctly according to industry standards, air blown fiber units have a lifespan of 25+ years. Our rigorous testing ensures resistance to environmental factors such as temperature fluctuations, moisture, and mechanical stress.
Do you provide samples for testing before bulk orders?
Absolutely. We encourage potential partners to request samples for pilot testing. This allows you to verify the cable's blowing characteristics, flexibility, and termination ease before committing to a large-scale procurement.
What certifications do your air blown fiber units hold?
Our products are manufactured under an ISO 9000 quality management system and comply with relevant EU directives. We can provide detailed test reports and certification documents upon request to support your compliance audits.
