Arial Fiber Cable

Arial fiber cable
Aerial optical cable is an optical fiber cable for hanging on a pole. Overhead cable laying method can use overhead pole original, save construction cost, shorten the construction period. Aerial optical cables are hung on poles to accommodate various natural environments. Generally used for long-distance line two or below two lines, suitable for private networks, optical cable lines or some special parts of the district.
Aerial fiber cable features:
1. aerial optical fiber cable is mainly used for grade two trunk lines and below optical fiber cable lines, applicable to flat terrain regions with smaller undulations.
2. overhead optical cables are mainly hung under the steel strand and self-supporting type of two kinds suspension, the current basic steel strand support type. The way of laying by hanging wire rod road (winding) erection or binding.
Overhead cable is easily affected by the typhoon, ice, floods and other natural disasters, aerial cables are also vulnerable to external influence and their mechanical strength weakening effect, so the fault of overhead cable was higher than fiber optic cable and pipeline buried type.
The use environment of aerial optical cable
The distance between the poles of the overhead line is 25-40 meters, the suburbs are 40-50 meters, and the other sections are no more than 67 meters.
Overhead cable suspension should be used for 7/2.2mm specifications galvanized steel wire, for the armored cable installation can be used 7/2.0mm or /1.8mm steel stranded wire.
The sag of aerial optical cable shall be considered when the maximum load occurs during erection and erection.
Overhead cable may be appropriate for remaining in the telescopic rod.
According to the design requirements for the pole, or put hanging remediation to meet the requirements of the original rod road.
Optical fiber cable hook spacing requirements of 50 cm, the allowable deviation is not more than + 3 cm. The optical cable card should be hung evenly, the hook and the supporting plate are complete, and the sizes of all kinds of optical cables shall select different sizes hooks.
Classification of aerial optical cable
1, hanging type: first use wire fastening on the pole, and then hang on in the hanging hook, the load bearing by wire cable.
2. Self support type: use self-supporting structure of fiber optic cable, fiber cable is "8" type, the upper part is self-supporting line, the load of optical cable is carried by self-supporting line.
