GYTA53-12b1 GYTA53-12B1 12 core fiber optic cable outdoor cable layer twisted fiber optic cable

Description :

　　Outdoor optical cables are mainly composed of optical fibers (glass fibers as thin as hair), plastic protective sleeves, and plastic sheaths. There are no metals such as gold, silver, copper, or aluminum inside the cable, and the outer protective layer is used to achieve optical signal transmission as a communication line. Pipeline laying is generally carried out in urban areas where the environment for pipeline laying is relatively good, so there are no special requirements for the fiber optic cable protective layer and no need for armor. Before laying the pipeline, the length of the laying section and the position of the connection point must be selected. Mechanical or manual traction can be used for laying. The traction force of a single traction should not exceed the allowable tension of the optical cable. The materials for making pipelines can be selected based on geography, such as concrete, asbestos cement, steel pipes, plastic pipes, etc. This type of fiber optic cable is armored with steel strips or wires on the outside and buried directly underground, requiring resistance to external mechanical damage and resistance to soil corrosion. Different protective layer structures should be selected according to different usage environments and conditions. For example, in areas with insect and rodent infestations, optical cables with insect and rodent resistant protective layers should be selected. Depending on the soil and environment, the depth at which the optical cable is buried underground is generally between 0.8m and 1.2m. When laying, it is also necessary to pay attention to keeping the strain of the optical fiber within the allowable limit. An overhead fiber optic cable is a type of fiber optic cable that is suspended from an electrical pole. This laying method can utilize the existing overhead overhead poles, saving construction costs and shortening the construction period. The overhead optical cable is hung on the pole and is required to adapt to various natural environments. Overhead optical cables are susceptible to natural disasters such as typhoons, ice floes, and floods, as well as external forces and weakened mechanical strength. Therefore, the failure rate of overhead optical cables is higher than that of buried and pipeline optical cables. Generally used for long-distance second level or below lines, suitable for dedicated network optical cable lines or certain local special sections.
