Installing duct fiber requires specialized techniques to navigate ducts (which may have bends, joints, or obstacles). The two most common methods are pulling and air blowing —each with unique advantages and use cases. The pulling method uses mechanical force to pull the cable. Fiber optic cable is usually (but not always) installed in an innerduct that provides mechanical protection for the fiber optic cable. Generally, the duct is available in plastic, concrete, steel, iron and so on. As fiber optic cable is sensitive to excessive pulling, bending and crush forces, much. Corning Optical Communications cable specification sheets are available which list the maximum tensile load for various cable types. We should always consider the restrictions established by different administrations related to this matter.
