Blowing/jetting distance is the maximum length of duct that a single blown run can traverse under typical field conditions. It depends on duct size, bend radius, cable diameter, friction, air pressure, and duct cleanliness, and represents how far the cable can be pushed through the duct in one operation without needing to pull or reconfigure. In standard OSP practice, about 2 kilometers is the commonly specified blowing distance, meaning that a single blown run is expected to reach roughly that length under typical conditions. If the run would exceed this distance, you plan staged blows or intermediate pulls rather than relying on one continuous blow. Shorter distances like 0.5 or 1 kilometer are possible in tighter or more constrained ducts, and 5 kilometers would require atypical conditions or specialized equipment, so 2 kilometers best matches the standard specification.
