What is the best height for China Unicom fiber optic cables above the ground

Urban Areas: 25–40m spacing (concrete poles, 10–12m height)., steel lattice structures). Factors: Cable weight (kg/km) Ice loading (up to 50mm. 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. Aerial installation is generally much less costly than underground construction also. Fiber in a duct solutions have a major aesthetic. The Fiber Optic Association, Inc. (FOA) was founded in 1995 to help develop the workforce to build the fiber optic networks to support a rapid expansion in communications and the Internet. Temperature Range: -40°C to +80°C for outdoor durability. Bend Radius: ≥20x cable diameter to prevent microbending loss. Here are some key considerations when selecting fiber optic cables: Single-Mode Fiber (SMF): Single-mode fiber. Overhead fiber optic cable is suitable for long-distance lines and dedicated network optical cable lines or some local special sections. It provides high tensile strength, good performance of mechanical and temperature, and low-cost installation. 5-foot sag for a 150-foot span helps cables handle thermal.
