The Overall Prerequisites for Elevated Fiber Links

(1) Ethereal fiber link ought to embrace steel strand support type in inclination. The design is raised by suspension or packaging (twisting) of shafts and courses.

 

(2) Ethereal fiber link ought to have the comparing mechanical properties, for example, shock opposition, wind obstruction, snow, low temperature and other meteorological burdens produced pressure, and have dampness resistant, waterproof execution. For the most part, as per the idea of the line, the climate and neighborhood conditions, regardless of whether utilizing the filling glue optical link can be chosen, however there ought to be a dampness resistant layer (aluminum foil layer).

 

(3) The distance between shafts of elevated lines is 35-40 meters in metropolitan region and 40-50 meters in rural region. The distance between shafts of above lines shifts with various weather conditions load zones. The most brief distance is 25m and the longest distance is 67m. The division of burden zones in China depends on wind, ice and temperature.

 

(4) The flying fiber link lines ought to take advantage of the current above post street and hang optical link. Its shaft street strength and different prerequisites ought to fulfill the structure guidelines of above correspondence lines.

 

(5) Electrifies steel strand with determination of 7/2.2mm ought to be utilized for suspension of aeronautical fiber link. The wellbeing component of the suspension line will not be under 3 (S > 3). At the point when the heaviness of optical link surpasses 1.5 kg/m, the distance between shafts can be decreased or 7/2.6 mm strands can be utilized in weighty burden region when the above laying mode is required for significant distance essential trunk lines.

 

(6) The flying fiber link ought to be chosen to meet the prerequisites of temperature qualities as per the utilization climate. – aeronautical laying ought not be utilized in regions underneath 30℃.
