Factors: Cable weight (kg/km) Ice loading (up to 50mm thickness)Urban Areas: 25–40m spacing (concrete poles, 10–12m height). Unlike buried cable, they excel in rural or suburban areas where trenching is impractical. To this end, overhead optical cable construction generally has the following eight steps. Choose the type of pole The basic pole height is 7m and the tip diameter is 150mm. Where reels are supplied with protective material fitted over the cable, the protection should remain in place until the cable will be installed. Deploying fiber above ground on poles or towers removes the need for underground digging and is particularly useful when the ground is uneven, rocky or both.
