Air Blown Fiber installations use what medium to move the fiber and reduce tension?

• A. Compressed air
• B. Water pressure
• C. Hydraulic oil
• D. Vacuum

Answer: (A)

Air blown fiber installations rely on a stream of compressed air to move the fiber through the duct. That compressed air acts as the propulsion medium, carrying the fiber along while forming a cushion that reduces contact with the duct walls. The result is lower friction and, therefore, lower tension on the fiber during installation, which helps prevent damage over long pushes. Water pressure would introduce moisture and potential leakage in the duct, hydraulic oil would contaminate the system and isn’t suitable for fiber ducts, and vacuum would create suction rather than a controlled push, not providing the necessary propulsion.
