How to check the span of an ADSS optical cable
The correct span length for your ADSS cable must match or exceed the longest distance between any two consecutive support structures on your route. Measure every pole-to-pole gap, identify the maximum span, then select a cable rated for that distance with an appropriate safety. To match ADSS fiber optic cable span design to your installation environment, you must evaluate pole spacing, wind and ice loads, voltage levels, and terrain before selecting the cable type. For aerial fiber projects, the correct design depends on span length, installation method, route condition, mechanical load, sheath requirement, and matching accessories. ASU cable offer a wider range of span. For a typical 12-fiber ADSS cable with a 8. At heavy loading conditions (1900 Pa wind, 12. Conversely, incorrect span. ADSS fiber cable works in an overhead state with two points of support over a large span (usually hundreds of meters, or even more than 1 kilometer), which is completely different from the traditional concept of "overhead" (the standard overhead suspension wire hooking procedure of the post and.
